What the developers have to say:

Why Early Access?

“Over 9000 Zombies! is a game about surviving and battling massive hordes of the undead and the best way to know if the game is on the right track is by player feedback. Guns could be rubbish, excessively powerful or too few in numbers and the players are always the best judges of this. This will allow us to maximize the amount of joy one can take from slaying the crowds of the zombies.”

Approximately how long will this game be in Early Access?

“A few months? This is a hard question to answer as it will depend on the kind of features players want in the game and how long it takes for them to be implemented properly. The current plan would be 2-3 months.”

How is the full version planned to differ from the Early Access version?

“More stuff. By the time Over 9000 Zombies! exits Early Access it should include things already planned like: more maps, vehicles, expanded multiplayer, plus anything else that people suggest during Early Access. The game currently has lots of room for growth and added depth!”

What is the current state of the Early Access version?

“Over 9000 Zombies! is technically still in Alpha but already has plenty of content to satisfy one's zombie killing desires. Single player is well established, including 20+ weapons, 6 defensive turrets to help battle the unending hordes. Two player online co-op is also in, although this is still very early so you can expect a few bugs with this initially.”

Will the game be priced differently during and after Early Access?

“While in Early Access the price will be lower, it's only fair when there might be some bugs along the way. Once out of Early Access the price will go up.”

How are you planning on involving the Community in your development process?

“Ideas, balancing, general improvements, anything to make your zombie killing experience more enjoyable. Over 9000 Zombies! is a game that can expand in various directions and the best way to get the right direction is to listen to the people playing and enjoying the game.”

Mini-Patch: a few tweaks

I made a few small tweaks to the game based on data collected from the prior update.

  • Changed the Kills Per Second achievement "Total Carnage!" to have a requirement of 30 Kps to reflect recent changes in difficulty.

  • Added support for 1280 x 1024 Monitor resolution as requested in the discussion forum. If you have a resolution you would like to see supported, feel free to just ask by making a post about it in the community discussion.

  • Slightly tweaked some values on weapons to make the steps of each tier more balanced and appropriate.

  • Fixed a graphical bug.

  • Lowered the range on basic zombie attacks by about 30%.

Update - v0.1.6.2 - A Swarm of Updates!

Over 9000 Zombies! v0.1.6.2 has been released!

The update will feature several key changes. The first major change is the game now uses an unlock-based Weapon System, replacing the old item-drop based weapon system. Weapons are now organized into four categories featuring multiple tiers in which each tier is unlocked by killing a required amount of zombies with the lower tier of gun in that category. Pressing the " i " key in game will bring up a display of how the tiers are organized, or simply kill enough zombies to fill up the green progress bar on the bottom of the screen to see what gets unlocked!

The second major change is a fully redesigned HUD. The graphics have been upgraded and the information it presents is more organized and readily visible. As stated earlier, there is also a new visualization to show your progress towards unlocking the next weapon.

Another major change includes a blended Zombie Spawning system mixing elements of the older system and the new system to maximize the amount of chaos. This will increase the action and chaos significantly as well as the difficulty, as there will be more zombies on screen.

Since difficulty has been increased we have decided to reset the Leaderboards to make the competition fair for new players, so now is your chance to establish yourself as the top Zombie Slayer!

There have been a multitude of other smaller changes as well.

  • New Unlock-Based Weapon System
  • New Heads Up Display and visualizations
  • Zombies Spawning System has been improved
  • Leaderboards have been reset
  • Various balancing changes to weapons based on their tier
  • Press " i " in game to access weapon organizational chart
  • Sniper rifle now has a 5 round magazine
  • Various graphical tweaks
  • Fixed a few bugs, including maps not resetting properly in Coop after a game over
  • Screen shake effects have been improved

Follow me on Twitter @LorenLemcke for the most recent information about updates and future plans! As always, feel free to post any feedback, bug reports, or questions that you may have on the games Discussion Board.

About This Game

This is Over 9000 Zombies! the game that uses special mathematical technologies to squeeze the maximum amount of undead chaos out of your PC. Experience top-down arcade action blown out of all reasonable proportions. How long can you survive against the unending zombie swarm?

No precision aiming needed here but you will need a variety of guns! To aid you in your fight against the undead there is a selection of 20+ weapons to enjoy. Burn'em, Shoot'em, Blow'em up, however you prefer to kill your undead, we have just the right solution for your zombie extermination requirements.

Standing around in the open is a good way to die in a zombie apocalypse, which is why you have some options to defend yourself.
Collecting scrap metal from corpses will allow you to build makeshift defensive walls and engineer automated turrets to help you cut down the crowds of zombies.

Sometimes you want to bring a friend along to an apocalypse, right? Well now you can. You and a friend can team up and battle the hordes via the power of the internet in 2 player co-op.
Prefer to play in the safety of your own home, then we have you covered with 4 player local co-op.

Nothing goes better with the sounds of death and guns than a rocking soundtrack, the intense electro-rock soundtrack from Clearside Music will keep you battling through the waves of undead.

As each day and night goes by the hordes of undead increase in numbers, ferocity and variety, who said trying to survive was going to be easy?

The title is no exaggeration. There's a lot of zombie carnage to be found here that will keep you entertained for hours. It's odd, because it's another zombie game, but for some reason, this one just appeals to me. I think it's because it takes little thought to play it. It's hard to explain. The point is, this game is awesome, and you should get it.

Early Access Review
Early Access games come in all manner of different states. I would say this one is in a perfect place to be entering Early Access. The game itself is already playable and fun, but I can still see where they can add even more in the future. The co-op works flawlessly, you don't have to jump through any hoops to play with a friend. I ran into very few bugs while playing and none of them were game breaking.

Over 9000 Zombies! is a Tower Defense like game, where the thing you're defending, in essence is yourself. You can place turrets, of which there are currently 6 to choose from, you can place a block barricade, and there are roughly 20 weapons to collect. Zombies drop health, grenades, scrap (with which to build), and on the rare occasion, new weapons.

I played only co-op, but I can see it being a little difficult for someone in single player. After one play through, we found ourselves searching for a more defensible building, as well as working out strategies to survive specific zombies on later, tougher days.

I look forward to future updates. I hope to see more turret types, more maps, a map editor, perhaps more zombie types and more zombie 'bosses'.

Overall, I highly recommend it!

Early Access Review
Over 9000 Zombies is a top down 2D shooter that is in development, and what was given to us on day one was great in my opinion, it is simple, it's easy to get into. Alot like Nation Red without the absurdly overwhelming difficulty to start out on. You collect scrap that zombies drop to fortify where you wish to dig in at, you can also build turrents and find new weaponry that zombies may drop. There are also an absurd ammount of zombies on screen at one time, there is veriations of zombies among the horde that don't feel so rehashed. A massive assortment of weapons that you can pick up that carry from game to game to make you stronger aginst the zombie threat plus new weapons to pick up ontop of that.

It is still quite in development, but I don't think it needs the early acess logo, it is solid enough to play on its own and cheap enough to afford, from what I see currently a great game is only going to get better, pop for it if you can afford it!

Also I would like to note that the devloper of the game, is listening to those who comment on it in the forums. They enjoy ideas and are looking to give the fans what they want to make a great game fantastic. Most developers really don't do this.

While not quite a review, here is an overview and first impressions video. This was recorded 3-4 hours before officially going on Early Access.

In it you collect scrap metal, grenades, health, and new weapons from fallen zombies and enemies. You can use the scrap metal to build turrets and barricades to try and survive the hordes of thousands of zombies. It actually seems to work quite well, though right now it does have a few good and bad points.

-Surprising amount of content so far.
-Music is nice and has good production value, gives good energy to the fights.
-Vast numbers of enemies and explosions going on. Tons of carnage in later days.

-The Map needs more variety or randomness, right now they are just a few main areas that just work flat out better than others.
-The difficulty curve can be unforgiving if you don't plan.
-Maps needs some sort of tile smoothering or filtering to make it feel less sharp.

Those are just some of my thoughts, so far it plays nice and actually pretty fun. It's certainly quite full for an early access game these days.

Edit: I had said that the grenade launcher stops working. What I didn't think about was it using actual normal grenades as ammo, and it appears to use one grenade for a full magazine. So thats not a bug.

Early Access Review
Below you'll find a comprehensive 3 minute review of Over 9000 Zombies. Below the video link, I'll summarise my thoughts on the game.
Over 9000 Zombies runs fluently and seems very polished compared to a lot of other Early Access games. Considering what it aims to do, combining a top-down horde-mode shooter with slight building mechanics, it does a very decent job. However, as stated in the video, I feel that the combination of static building and dynamic horde mode does not work nicely together, as your character grows into being nothing more but another turret, static, waiting for the hordes to be taken apart by your armoured base, instead of actually being on the run, taking advantage of speed, weapons or temporary buildings. Maybe I just expected a more thrilling or let's call it reactionary experience.

A very fun and addicting top-down zombie shooter. This game is fantastic in Co-op. Many different weapons to use, different zombie types, different turrents to place to defend your position, and more to come since it's in Early Access. Also the soundtrack is freaking epic. I have high hopes that this game will turn out even better with more content and maybe more modes to play? Either way, very awesome game that I reccomend to any zombie shooter gamer. Worth the price in my opinion.

Edit: Also the Developer(s) are very kind and helpful for any questions I had and responded to me directly with more help than I expected! :) Thank you again Loren!

I've played a whole lot of zombie survival games, so it's rare that I see anything new in these sorts of games that I haven't already seen dozens of times. Over 9000 Zombies doesn't really bring anything new to the table, but its straight-talking no-frills approach to the genre is laudable. You're plopped down in the middle of the hordes, and told to shoot and build your way to victory. There's a bit of tower defense going on too, through which you can put together a base to keep the undead back, and then hope for the best. My video playthrough can be found here:

Early Access Review
There once was a series of flash games called "Endless Zombie Rampage". It was a simple game, consisting of shooting zombies in a parking lot. The weapons got better, the zombies got harder, and it was fun.

But it stopped, and that wasn't good.

Now, a successor has arisen, and it's called "Over 9,000 zombies". Weapons, turrets, walls, thousands of zombies to kill, an expansive map, far surpassing it's predecessor.
But unlike EZR, this game never stops.

In EZR, you got a breather. A chance to go to the store, go to bed or go back fighting, but it was a break in the day.
In Over 9,000 zombies, your only solace is death. You get a minute between waves, where zombies no longer spawn, then it's back to the frantic shooting, dodging, and repairing that is O9Z.

And I for one, wouldn't have it any other way.

Early Access Review
It's not bad if you're playing to reach Day 10, after that it just becomes an (easy) grind-fest. I made it to day 27 (12th place on the leaderboards for kicks) before I gave up. Once you get a powerful enough weapon, you can just stand there and hold the mouse button while using your other hand to feed your mouth with chips.

I can see this game getting a lot better, but:

Nays (as of now):
- I found very little use for most of the weapons, there's a lot, but you'll probably never use them.
- Items that give you temporary stat bonuses don't last long enough/aren't very interesting, I couldn't justify picking them up.
- Block placement is fun, but I never seemed to be able to collect enough resources to build more than 8 blocks at a time.
- Music starts to get annoying, it's not a bad track, I just wish there was more than NUNUNUNUneeeNUNUeeeeeNUNU...
- You can't be bothered to look at the UI early on, it's very small and should be more noticeable.
- The cursor/crosshair is also difficult to spot, I never know where it is after blinking.

- The A.I works very well, I can see there is some AGGRO involved.
- Bullets don't simply go straight, there's some realism.
- Hit testing is spot on for walls/structures.
- Various mobs, the game is not limited to zombies.
- I don't regret paying $4 for this.

Basically, this is Bird's Eye Serious Sam, but the weapons will eventually need some major balancing.

- Map Maker, especially for a tile-based game like this.
- More items: fences, mines, det-bombs, bla bla.
- Bosses, bosses that don't like it when I spend that past 3 hours camping in my 7x7 structure.
- Leveling and more stats... Make this game better than Diablo 3!

this game is simple and fun. slaying zombies everywhere with so many guns. grab some buddys for twice the fun. build to keep yourself safe and your buddys. all I really want to know about this game is what will the change or add once the games out of early access. this is the game for you if you like killing thousands of zombies and having a bloodly (get it?) good time.

Pretty fun retro-style zombie shooter. Killing off hundreds of zombies at any given time, collecting different weapons, power-ups and scrap metal used to make turrets and fortifications and some challenging gameplay make this a fun time.

This game is really intense and good. It's a lot of fun and I can only see it getting better. At the time of this review I have not played with any friends but I can only imagine that it makes the experience better.

Good retro graphics, a nice soundtrack, retro sound effects make this game a must have for the retro gamer. If you like top down shooters then pick this up, you won't regret it.

At the time of this review as far as I can tell there is only one map, which is kinda bummer, but devs plan on adding more plus they plan on adding steamworks support so players can make their own maps.

Great time wasting game.
After 14 hours I have just made it to day 13 by myself, and suspect that I will need a fellow combatant to get any further (day 20)

Visually its not a great game, and the menus and interface could be better. That said, its fun, engaging and addictive.

If you like top down survivor shooters - add this one to the list
