About This Game

Lock, load and let the gibs fly in OTTTD, a Tower Defence/RTS game with RPG elements that pits you against some of the weirdest creatures in the multiverse.

OTTTD stands for Over The Top Tower Defence, and you'll see why when you're blasting 9 kinds of hell out of a Cactus Ghost that's making a beeline for your battlefield HQ. You play as a commander for HEROCORP™, the 4th largest private military organization in the galaxy. A long period of peace has left the company coffers a little bare so the science division developed Trans-Dimensional Rifts, opening up lucrative opportunities for war in other universes. It's like Starship Troopers meets Stargate meets Spaceballs, with way more explosions!


Ridiculously definitive edition
Prepare your eyes and ears for incredible deluxe-ness! Featuring crisper sound and high resolution graphics, the PC release of OTTTD will leave you feeling like you've actually stepped into an alternate universe and started blasting everything to smithereens.

Deep RPG Mechanics
OTTTD lets you choose from 7 hero classes to make up your squad of 3 battlefield employees. The more action they see the more XP they earn, giving you the chance to level them up through custom skill trees, including powerful combat abilities to unleash during the fight.
• 30+ active abilities
• 40+ passive skills
• 30+ equippable weapons
• multiple armor options with stats to suit your play-style

Weapons! Weapons! WEAPONS!
With 12 tower types to build and 6 different firearm classes, HEROCORP™ has got the hardware to ensure you can wreak havoc in your own personal style.

Disgustingly varied foes
The range of enemies in OTTTD is wide enough to soothe even the itchiest trigger finger. Floating eyeballs? Check. Gunclams? You know it. Giant armored Wartoises? Of course. You'll even go toe to fin with a giant flying shark, and show the mythological Kraken who's boss!

The Story
The year is 2136. You work for HEROCORP™, the universe’s 4th largest private military force. Your job is to “preemptively defend” the Earth against alien dimensions. As long as you complete the missions under budget and fill out the TPS reports in triplicate, everything goes smoothly.

Is pre-emptively defending Earth ethical? Who cares when the money’s good!

Deluxe Edition

HEROCORP understands the needs of the more discerning battle commander, hence the Deluxe Edition of OTTTD. In addition to everything in the pre-order, you'll get the Deluxo weapon and armor sets. Recently developed by our Lab Division, the Deluxo Range gets more powerful each time your soldier levels up, making it worth its weight in requisition forms. We'll also throw in a Deluxe Wallet, with 69,000 coins and 11 medals to buy yourself something nice.

• Dexluso Armour - Armour that gets stronger as you get stronger
• Dexluso Gun - Gun that gets stronger as you get stronger
• Deluxe Wallet - 69,000 starter coins and 11 starter medals

OTT Edition

In addition to everything in the Deluxe Edition, the OTT edition comes with rare Cheese Armor set forged by our Dairy Division, which helps your soldiers get more XP and coins on the battlefield.

You will also receive these bad boys:
• An Art Book PDF, full of concept sketches plus more visual treats.
• OTTTD poster artwork. Looks amazing on 100% of walls.
• 3D Printer files for the HEROCORP soldiers, so you can battle command IRL.
• Your name in the credits as an OTT supporter. Welcome to history, baby.
• An OTT Wallet stuffed with 101,010 coins and 42 medals, to give you the financial edge on your enemies."

***Written using a key provided by the Developer for review purposes***

OTTTD (Over The Top Tower Defense) is a tower defense/RTS game with RPG elements. In OTTTD you assume the role of a HEROCORP™ commander who is waging war in another universe for lots and lots of money. This universe has some pretty crazy creatures roaming around in a couple of different areas and you'll fight them over the course of 25 missions.

+Nice design and cartoony art style
+Great soundtrack
+Good camera controls
+Lots of gore (the amount of gore can be changed) and gore, as well as shell casings, stay on the map for a long time before disappearing
+You get characters to fight on the ground who have special abilities and have skill trees to unlock more abilites, skill points are awarded each time a character levels up after a mission
+Good voice acting
+Variety of unique, and some not so unique, enemies
+Four different basic towers, each with two main upgrade ranks and a specialisation
+Has some really funny lines in it
+It's very challenging without feeling too difficult
+You can buy weapon and armour upgrades for your units
+Each of the twenty-five missions has a story mode as well as an endless mode

-Towers can only be built at predefined locations which takes away some of the fun of figuring out what tower is best where
-There's no collisions between enemy units so faster units move straight through slower ones rather than stacking
-Weapon and armour upgrades are extremely expensive
-There's only three different environments for the twenty-five missions


Despite its imperfections this is a great TD and a must have for all TD fans.

Tower Defense is one of my favorite genres, and this is one of the best TD games on steam.

To start It has tight controls, and a smart hotkey layout. I found this to be the main problem with most of the tower defense games I have tried so far.

The only issue I have with the game is that tower placement is restricted to pre determined areas, this lowers the difficulty of the game and the strategic aspect. However as you progress further It becomes less of an issue as the maps become bigger.

I would rate the game 8/10

10/10. This is tower defense done right. I have nearly every tower defense game on steam. It's my favorite game genre. I just played through the whole campaign of OTTTD, and it was the most fun I've had playing tower defense in a long time! I've already started replaying maps just for the fun of it. There's also Endless mode.

OTTTD is an excellent mix of TD, RTS group tactical play, with the leveling elements of RPG. You have all of the classic tower types, plus you have several characters, and you can bring three of them onto the battlefield and control their movements and their special attacks. Each character is unique. The whole game is unique, with a style all its own, while still feeling like a classic tower defense game with lots of extras.

Everything is extremely well-balanced. The maps are challenging, yet certainly doable if you make wise choices with your characters and towers. Each character brings something different, and some of their abilities play off of each other and the towers. There is a lot of variety in the maps. Some characters are more useful on some maps than others, and some work better in certain group combinations than others.

There's a lot of high quality game here for the money, especially with Endless mode.

This is a phenomenol tower defense game. The music, the gore, everything is just as it should be. Where else are you gonna fight a knife wielding octopus on a Harley? It's super tough, and at first I was getting stomped. Best bring your A game with this one....

OTTTD is a passable tower defense game. The graphics are clear, sometimes even fun (so much gore!) but the animations are stiff and lifeless. The gameplay is solid and smooth, but carries over the worst of mobile game tropes like static hard points for towers and grindy unlockables. The music gets the job done, but I wanted more. This is one of those games that makes me wish Steam had a "meh..." button, because it really isn't bad, it just doesn't merit my recommendation.

I've now played enough of this game to know I love it. It's along the lines of Kingdom Rush, but utilizes 3 deployable heroes (company employees) rather than just one. Thus you have lots of combinations of employees to try, and they have skill trees that have passives and clickable skills - you only get to bring two skills to battle, but the skill tree offers about 5 different active skills per guy. Upgradable weaps and armor round out the toons as well... idk if this was a micro app mobile thing at one point, but it seems they start you out with better than worst weaps & armor, which is a bit confusing. But you still have about half the weapons to look forward to (grind for).

The towers have a lot of variety, although mostly are just straight destructive... but I still haven't unlocked everything. Standard fare of mg, energy, rockets, air, and slow as the core towers, but there are a few variants of each that offer a nice variety.

The game is hilarious, and if you don't laugh at the Schwarzeneggar's character lines at least a few times, you suck, cuz they are funny. :3 While the game is funny, the psuedo 80s style "shoot first, shoot more later" over the top violent trope is beaten to death, and does get old. Still, they do it well.

I LOVE the gibby-ness, and the fishy-ness, and the art style in general, it's awesome. I could mention a few ticky-tacky things like no sfx slider (but yes music slider) but whatever, it doesn't really matter. The game has what it needs. It hasn't been all that difficult but I'm only a few hours in. To me it seems difficulty seems to be scaling just about perfectly.

This is a definite Yes recommendation.. easy buy at 75% off or even at full cost, not one to regret.

Just don't be Steve from accounting. (you'll see.)

Yeah, it's alright. I find it a bit repetitive but the heroes aspect of it makes it a bit more interesting than the average tower defense game.

You are constantly poked in the eye that this is a port of a mobile game, but the lower-speced graphics with the 60fps cap means I can play it on my laptop without it overheating after the first five minutes you kind of get over the graphics and focus on the gameplay. Fortunately that is the only allusion to the more negative side of mobile porting, everything else has been smoothed over.

Some things I'd have preferred to see in the game though, would be able to zoom out more for a wider FOV, and ideally sync my gameplay progress between Steam and mobile.

This game seems to be a good tower defense game. The main negative comment is after playing the game for 1 hr, it seems the heroes die easily and take 45 min to respawn. I had to quit the game and wait for the respawn because the heroes are necessary for level progression. This smacks of mobile ftp gaming timers.

After many more hours of playing, I have learned how to keep my heroes alive. I would recommend this game to my friends.

One of the best tower defense games I have ever played. Now mind you, I have played a LOT of these types of games. The only con of this game is you can't pick where the towers go - (it's predetermined) but it also means you have to have more strategy in actually killing them. It also has really good graphics and you can even upgrade everything!

TL;DR : This game is good. Recommend if you love tower defense and strategic play.

I played the demo before and well I already was sold when i played the demo.

This game is pure fun and enjoyable. Even if you just only watch the details like when you kill something - yeah, it gets ripped appart and the (body)parts are flying around on the map. And next to this you have amazing towers that you can upgrade, Hero's (characters with great weapons and special abillities), and neat maps. This game is surely worth to call a Tower Defense, the gametitle fits perfectly too.

Worth your money, even if you pay full price.

I've played for 2 hours and made it to mission 11 of 20. I didn't realize it was a PC port of an android title until after I started playing, so at first I wasn't sure that it was a good choice. It turns out however that;
- It's pretty fun and has some cool and sometimes pretty amusing features
- After playing the standard edition, deluxe and OTT versions don't sound worth it at all

At first maps looked like they were way too small and felt cramped. Tower placement is restricted to spots around the map marked with an X. Also you can't increase the speed of the game. None of these were really an issue in the end later maps were big enough and you just need to make sure you have a good combination of different types of towers in limited locations where you are able to place them. You also have a pool of up to seven heroes, three of which you can take onto the battlefield each stage. I unlocked five of them by stage ten. They can be ordered around the map to attack enemies and also have special abilities which can be upgraded as your heroes level up after completing stages. My favorite heroes were the recon and rocketeer. The rocketeer can periodically call in a powerful cruise missile strike anywhere on the map. The recon was able to mark targets so that the rocketeer and any missile turrets could fire missiles at them even if they were out of range. That was my favorite thing about this game. Not every tower defense game has stuff like that. Also you can buy weapon and armor upgrades for your heroes. This is how you spend your coins and medals. I just bought the standard version of this game so I earned all my currency just by completing stages. Some of the stuff is pretty expensive especially the armor, so I could only afford basic weapon upgrades. This didn't really seem to matter, I still kicked ♥♥♥ without better gear. I don't see why you would want to get the deluxe or OTT editions of this game just for extra coins and medals. 100,000 coins will only get you two sets of basic armor... You also use medals to resurrect fallen heroes between stages, but so far my guys hardly ever died. I don't seem have a shortage of medals. Again another reason why I don't see the point in paying more real money for coins and medals. Why would you pay for extra currency in a non free to play single player game?

Some of the enemy models were really amusing. There are giant disfigured teddy bears that shoot laser beams out there eyes and obese green skinned cleaver wielding zombies that ride mobility scooters lol amd puke gibs all over your turrets and heroes. Also I really liked some of the dialogue, one the heroes sends up Batman 'my throat hurts... do you have a throat lozenge?' lol

Maybe there are actually people out there who want the extra art and stuff. But the Deluxe and OTT editions are over double and triple the price respectively of the standard edition. This problem is easily solved by just getting the standard edition lol, which I recommend trying.

My original review was fairly critical of this game due to the controls. Within a short period of me posting my review the developer personally responded to my criticism, thanked me, and then a week later released a patch that addressed the vast majority of my complaints.

Seriously, at this point I'm incredibly impressed. The game is quite fun and the developer clearly cares about their product.


This game is pretty solid, even with the little bit that I have played. At this point I am really wishing I would have bought this on iOS or Android though because the PC ports has some issues with the controls that leave me feeling frustrated because I feel like I am playing on a touch screen but I am forced to use a mouse as an intermediary. So much standard PC game design convention is thrown out the window just to make this a fast port.

1) Everything is accomplished via left-click, including moving your hero. Let's face it, the standard PC control for moving your hero from point A to point B is to right click.
2) The battlefield camera is incredibly myopic and should be able to zoom out a bit farther on larger screens.
3) The battlefield camera doesn't auto detect your mouse position and start scrolling the screen over when you mouse gets to the edge of the screen. Instead you must left-click on an empty area of the map and then drag the screen over as if you were using a touch screen tablet.
4) The scroll wheel does nothing useful. If it isn't going to zoom in and out very much, It should probably be set up to scroll through your heros in the same way as the tab key does instead.
5) When you have a special ability queued up your cursor doesn't give any indication that you are in that context. If you're activating a special ability and are moving the mouse we tend to expect our cursors to reflect what is about to happen when we click.

As I said before, I really like this game. On mobile I would really, really enjoy it. Unfortunately the PC controls are just nothing more than a sloppy port from a mobile game. I'll tolerate the annoying PC controls because I'm enjoying it regardless

Fun, thoroughly enjoyable game, but doesn't feel quite right on PC.

OTTTD is mainly a tower defence/rts/rpg hybrid. You build your towers in fixed spots, level up and unlock abilities for your characters, then mess up a bunch of enemies.

First the positive. It is a very quirky, characterful game. I've smirked on a number of occasions when the next bad guy starts walking down the paths. If undead teddy bears, giant flying shark fortresses, and 'shanktopuses' are your thing, then get this game!
Music and sound effects are good, as is the voice acting. Didn't turn me off or make me cringe, which as a sound designer myself, is a really good thing.
The whole atmosphere is great, and whoever wrote all the little jokes on the items/upgrades/achievements needs a pat on the back.
And of course, gameplay is smooth, easy to get the hang of, and quite intense in the later stages.

So, it all sounds really good, right? Well it's important to know that this is technically a port of a mobile game. I was aware when I bought this, and it certainly shows, but it's not necessarily a bad thing...in places.
For example, it is easy enough to get coins and medals (the respective currencies) in game, and the option for microtransactions is absent (or at least, I couldn't see it). This is obviously a big thumbs up, although it makes the fancypants versions for sale kind of obsolete unless you're into the extras.
However, when a character dies, you have a time limit before you can use them again. You can speed this up at the cost of a medal. To be honest, I wasn't that bothered by it initially, as earning medals is easy, but that changed once I unlocked the first endless level. If your characters die, they gain 0 experience AND you have to wait for them to revive. Getting no exp from a 15+ wave run is one thing, but then having to wait 45 minutes (without using a medal) to revive is another. Not cool.
NOTE: After playing it a little longer, this no longer becomes an issue, as you'll have a huge surplus of medals.

Another example would be that, in order to pan across the stage, you actually have to click and drag, like using your finger on a tablet. Not a bad thing, but I'm more used to the rts-esque camera-follows-the-mouse deal.
There's also little in the way of settings customisation, although if you bought this game with that in mind, then I don't know what you expected.
A lot of these small things constantly remind me that it's a mobile port. Too many control/mechanic decisions feel a little foreign to the keyboard and mouse. It's unfortunate that these small issues glares over an otherwise fantastic game, because I've thoroughly enjoyed every moment of the actual gameplay.

If you can accept that, then you should definitely check this out. Definitely worth the current price (the standard edition anyway).

I was a bit skeptical of this game given its mobile origins, but I am happy to report that my fears were unfounded.

OTTTD is incredibly awesome! The plot basically boils down to soldiers being out of work in a utopian society, so a company hires those soldiers to fight wars in other dimensions before the wars even happen. This means that the bulk of the game's plot sees you traveling to foreign planets and killing anything that moves.

As is somewhat typical with modern tower defense games, you unlock more towers and more tower upgrades as you progress. This ranges from the typical machine gun tower, missile tower, etc to eventually things more exotic things like death rays.

There's a sort of rock paper scissors aspect that starts to take shape in-game as some enemies are vulnerable only to specific attack, as well as introducing flying enemies etc. This means that you can't simply choose one type of tower and max it out to steamroll each level.

What makes OTTTD different than a lot of other tower defense games is its sense of humor and the soldiers which I previously mentioned as part of the plot. For each mission, you can bring along three soldiers. They function and unlock similarly to the towers except that they can walk around the map. Additionally, each soldier has their own set of skills, with skill trees that can be filled out as they level up. It's honestly difficult to decide if you're going to take a soldier into battle with strong offense or take a weaker character who can boost tower abilities. It's extremely well balanced and each soldier feels different. You can also buy different equipment for each soldier that will change their stats and appearance.

What really helps everything in the game feel different is its sense of humor. Each character has their own personality and set of dialogue that they will say as battles go on (though it will repeat somewhat frequently) with some characters talking about how the battle is boring them, how violence is bad, etc. It helps the characters feel a little more important than just walking towers. There are several planets to wage war on with a variety of strange enemies and unique environments. It kind of feels like if Starship Troopers was made into a 1980's cartoon in a lot of ways.

There are over 20 main missions in the campaign, with several boss battles scattered throughout. As you progress, you unlock stars which can be used to unlock levels in the "endless" mode.

Overall I feel like the game is worth the money and doesn't suffer any major drawbacks from its mobile origins.

10/10 Would invade alternate dimensions to create a war economy again.

Over the top tower defense, or OTTTD, first released on mobile and now an Steam has loads of issues. More info either in the following video or below that in written format. Choose whatever fits best for you.
Graphics: OTTTD uses a comic artstyle with plain colours. Considering the low polygon count and the simple texturing, OTTTD still manages to look passable. The special effects and the lighting overall is visually outdated though.

Sound: The music is repetitive, the sound effects are flat and boring, and especially the commentary of the soldiers is very cringeworthy. The game tries really hard to be funny, but falls short and never came close to tickling my funny bone.

Gameplay: The gameplay shows the mobile roots of OTTTD clearly. It's overly simplistic with it's fixed positions for towers. In general there is barely any strategy to OTTTD except mixing towers due to the three different damage types (impact, electricity and flame). There is no timing involved when to upgrade and no incentive to hold back money if it is not needed.
The heroes in OTTTD gain experience and thus can upgrade their skills, which are sadly mostly boring stat upgrades and seldomly add any interesting ideas. With the earned gold from missions, you can also buy new weapons, which are heavily overpriced. This again comes from the roots of being a mobile game. In-app purchases and expensive items to push players to paying even more money than "only" paying for the game. This continues with timers on dead heroes, which can be skipped with the special medal currency and does not stop in the actual handling of the game, as everything, yes, EVERYTHING is just controlled by the mouse and the left button. No right button, nothing else. You can clearly imagine that clicking something else instead of doing what you wanted to do happens all the time.

It seems to me that the developer took the original mobile game, created a quick port (which runs like ♥♥♥♥, as the game drops below 15 fps sometimes on my machine that can run Skyrim at Ultra with 60...), even had the audacity of more than doubling the price compared to mobile without even adjusting the balance.

Do not buy this game, save your money and instead play some of the great free Tower Defense games available (GemCraft for example). Thanks for reading!
