About This Game

Fight off hordes of monstrous mutants created from a strange cataclysmic event in the new tower defense game, Prime World: Defenders. Join a group of exile treasure hunters who have ventured into the capital of an ancient empire, vast with mystery and danger.

Prime World: Defenders merges classic tower defense gameplay with collectible card mechanic. Your towers, your spells, your traps - all are magic cards, that you can collect and upgrade. You'll have to develop your own strategy, because you'll get your random set of cards after each battle.

Freeze, burn, poison, explode and slash countless enemies that will try to stop you from gathering artifacts of old kingdom. Choose your cards carefully, play them strategically and expect some heavy resistance along the way – from small and almost harmless mutated fungi to powerful giant goblins and nagas.

Did we mention? In addition to story-driven single-player campaign Prime World: Defenders has randomly generated missions, newly added endless mode and New Game Plus!

A blend between MTG and defense grid.
You can really play this game at your own pace, you can spend your time on creating a great defense strategy or just grind to get better towers, it's best to just do both.
This game is addiction oriented and has the fairness of a mario party game, but if you are tired and still crave that feeling of doing something, this game really does that...
If you want a more skill based TD game, play defense grid, if you are a perfectionist, play spacechem or gnomoria.

a great TD game. Colorful, fun towers, and a interesting card based upgrade path that would have been easy to add microtransactions to, but thankfully they have not. Bonus points for not being a crappy company.

How many of you enjoy card collecting games like “Magic: The Gathering?” How many of you play “Defense Grid” and “Sol Survivor” religiously like your life depended on it? If you raised your hand to both of those questions, then there’s no doubt in my mind that you’ll take a liking to “Prime World: Defenders”. This game reminds me a bit of “BattleForge”, a card collecting real-time strategy game that I was heavily invested in for quite some time. In this case however, you’ll be collecting cards that will form your tower defense arsenal and be tasked with slaying mutants and baddies by the thousands.

Overall, I really enjoyed my experience with this game. I’ve thrown hours into this game and have been showing no signs of slowing down any time soon. “Prime World: Defenders” is an incredibly addicting game that I’m glad to see has brought something new to the tower defense table. Yes, it’s a bit grindy…but I’m finding it to be the good kind of grindy. I also want to praise the game for not including any sort of real money store or microtransaction system, which would be very easy to do in this particular type of game. Everything purchased in the game is done via coin, which you’ll be earning as you play. The mission generator (which you’ll see after the first few missions) adds almost unlimited replayability to the game. My only real complaint (if you could call it one) was that the combat and tower animations were a bit generic. While pretty, I didn’t feel “wowed” by the towers I placed or the enemies I saw…they just simply served their purpose. If you’re looking for the bottom line, then I’ll simply say that I highly recommend it, especially for the ten dollar price tag that it currently advertises.

I prefer tower defense games without grinding or out-of-match powerups or such.

The game is a good bang for your buck. If you enjoy TD, and need a good 10 minutes of free time, this is the one to pick up. There are skill points, evolving towers, and an enjoyable card system. There is currency which allows you to buy random chance drawings at different tiers. The graphics are very good considering the price. The towers are not very balanced, but the tiered system allows basically three levels of rarity. The metascore is not a fair score. While there is some grind, that is kinda the point of TD games. You grind for better towers and skills. You can still progress far without having to grind as much, but you need to get at least 1 or 2 "pink" cards (tier 3) to really shine in grinding/progress.

I have about 50 hours in the iPad version as well which seems to be better in terms of log-in rewards but worse in terms of glitches/freezes.

Lets start of by saying that i havent played a lot of tower defence games but if a fair few have the quality that this game does then i think i will be playing a fair few others.
When i started playing the game i was like "I really like the setting" (huge fantasy fan me) "but do i really like the style of gameplay that this sort of game has".
Then i watched as time went by and i realised this is exactally the sort of game i love to spend time with,the setting is pure fantasy and is well represented in game with the graphics,sound and script.
The game plays out from battle to battle and you gain coin and different cards that you can use in battles defending the entrance that the demons (from bouncing heads on sticks to exploding frogs-GO FIGURE) try to reach and if they do so in a certain number then its "GAME OVER MAN" (couldent resisit the quote there).
The cards are also used in between levels in upgrading the towers you have,and beleive me when i tell you that this plays a heavy part in the game as dont upgrade and you are not going to proceed any further than where you are at that certain point in the game.Grinding plays quite a huge role in the game and is an important part of being able to upgrade the equipment you have so you can get that one level closer to the finishing line and the demon who seems to want your head on a pole.
Like i have allready said i really liked the game and after playing for a while (havent quite finished just yet-but dont think it will change my opinion on the game as i will still regard it as a game i would reccommend to anyone with a love of tower defence games) then decided to buy another tower defence game (well the pack) ANOMOLY 2 and found that i really like that game also.
So sometimes it is good to play games you arent used to as you then find that sometimes a change can be just what you needed and that a game style you have never played before can get you gaming in ways you never thought you would.

While an excellent tower defence game, which includes RPG and card collecting elements, it unfortunately contains far too much grinding, and doesn't progress quickly enough. So why am I recommending it? Well, because for what you get out of it, Prime World: Defenders is certainly worth playing. :3

Fantastic twist on the modern MMOBA that has sweeped the PC gaming world. Combines a unique RPG aspect to the game, with a fully customizable set of characters in which you must progress through and unlock. Of course, as with any free to play game, you can always spend daddy's pay checks to further advance your progression within the castle, however, by doing this you really are eliminating one of key features that this MMOBA offers, in which it's competitors have yet to incorporate. 5 out of 5 stars. I've been hooked since day one, and nearly 3000 hours of game play later, I'm still not finished progressing my heroes to the ultimate "End Game" builds.

I just had to make a comment on this game after reading the other reviews and seeing that this game got a very low

Almost every negative post on this game complains about the "grind" yet has less than 10 hours total even played for the game. Yes, to get the "legendary" stuff in this game you must actually play the game!?!? A shocker, I know. To think the devs actually want you to play the game that you just got. Zzz...

Sarcasm aside, this game really is pretty fun. It blends TD, char lvling to gain new skills and also the collecting of cards to gain access to new towers and spells. You then sacrifice extra cards to towers you like to make them stronger. I honestly hope to see more games like this. This game is just as ground breaking to TD as Dungeon Defenders was. The addition of actuall loot in my mind is what makes it shine, but clearly other lazy folks don't agree and just thumbs downed the game without even trying. Granted I've only had it for 1 day but I've logged 10+hours in that time & can't wait till I wake up later to play it some more. As far as the metascore I really am stumped, this is the most fun I've had on a game in awhile and all for under $10. If it goes on sale again it's worth a look.

A mix between a card-collecting game and tower defense is an incredibly awesome concept, but unfortunately this game is very poorly executed. The difficulty spikes are too steep, requiring you to grind "challenges" (which are really just previous levels) constantly. By the midway point of the game, you are literally spending >90% of your time just grinding. If there wasn't so much grinding, this would be a great game, but would probably only last three hours. As it stands, it's a bad 30 hour game due to the 27 hours of grinding.

On the upside, the music and graphics are well-done. The variety of towers is also pretty good.

But oh lawd dat grindin'.

***Shame on you Valve for remaining to offer this as a pay title when its Free-to-play on both Android and Apple Markets!!***

Don't get me wrong I like the game play it self but save your money and check it out there for free. It could only be worse if you happened to pay the full price for this game.

Steam does offer a Free-to-Play Prime World RTS Game here, but I do not care for it:

Check out the free ebook there as it was what pushed me to waste my 2 bucks on this TD Game!

I really wanted to like this game because of the whole tower defense thing and how nice the game looks, but it is VERY, VERY, poorly executed. It starts off fun for the first half... You get to upgrade towers and combine powers and unlock new abilities... All very nice...


The baddies are in a constant state of "better than you can ever be" near the middle of the game. As you are upgrading towers, like in other tower defense games it should be EASIER to take out baddies so they just throw more baddies at you so you can then upgrade towers more, but in this game they not only throw more baddies at you but the baddies are near invincible and require HOURS AND HOURS of grinding to finally beat. Even with upgrades and such, the starting "prime" money/resources at the begining of each level is insanely low for the amount of powerful baddies that show up even in the first wave... The amount of prime you get from each kill does not go up with the difficulty increase and health increases the baddies get as the game progresses, so it makes it even harder to upgrade towers and such without pointless hours upon hours of grinding. Also, the types of towers that show up after the midpoint are completely random, so you may get some decent towers in a playthrough or you may never see those towers at all! It just feels like a poorly executed port from a mobile platform "free to play, but pay to win" type game at that point. I mean I had towers upgraded that could do 5000+ damage in a single shot and it couldn't take down the weakest swarmers.

I really cannot recommend this game because of the insane difficulty curve that spikes in at the midpoint of the game; it goes from being fun, to being a decent challenge, to being an automatic rage quit. Maybe I will revisit the game and give a better review if the devlopers ever fix the balancing issues. (DEVS? If you are reading this, play the game 'Defense Grid" that is how a tower defense game should be done.)

It starts out fun. But after a certain point, you'll have to grind filler levels just to level up.

This game is not without flaws, and your enjoyment of it can depend greatly on how you like it's mechanics. Most crucial among those is a progression system that allows you to level up your towers between missions through a collectible card system. You can buy additional cards as well as boosters with ingame currency (no microtransactions whatsoever in the steam version) and use those to evolve your towers, unlocking the ability to upgrade them during missions, or infuse them, making them more effective. Different tower cards also have different rarities, with some being straight upgrades from their common versions. This leads to the first major flaw with the game, as the card rewards for side-missions are random, leaving you hoping for a specific tower to drop because at some point in the game, about 10-12 story missions in, you will hit a brick wall of difficulty. Once you get the next 'tier' of basic towers properly evolved and infused it becomes easier again, but getting these towers is mostly a case of farming sidemissions in hopes that RNG will bless you with the right rewards. I feel the upgrade system worked well inherently, but adding tiers to the towers completely broke it.
Difficulty tends to be all over the place in general. For example, finishing the normal mode of the game unlocks a heroic mode and two extra long survival missions. But with the towers required to beat the last level I had zero difficulty in the survival missions, often mashing the rush button to send in more gits because my towers ground everything to paste from start to finish. The heroic modes also felt hugely dissapointing, as I was able to blitz all of them with next to no effort up to the last level, which I overcame with two retry's and a bit of tweaking the tower placements.
The missions themselves however, are well-built for the most part, with the only hiccup being the randomized levels you get for your sidemissions. The game essentialy re-uses previously finished levels and adds random buffs to some tiles and inpassable rocks to the other. This meant you couldn't rely on a single layout and had to adapt, which greatly increased their replay value. Admittedly it could benefit from removing the first few levels from the map pool, since they're so small you run out of things to build or upgrade halfway through the harder sidemissions and can only sit and cast the odd spell, waiting for the waves to inevitably overrun your defense.
The towers themselves start out rather bland with the basic all-round tower, the slow tower and the anti-air tower, but later tiers add some much needed variety, with the highest tier offering some interesting options to mix and match into all new ways to make the Touched's lives impossible.
The Touched is the generic enemy faction in this game and consist of a collection of fantasy villains like kobolds, ogres and trolls. The only remarkable enemy is the pink floating marshmallow... thing that occasionally teleports forward and suddenly sneaks past your defenses. No really, you'll know it when you see it... and then you'll rage.
The game has a story and a linear set of missions to follow along with that, but it's cringeworthy at best. There's no major twists, even if the game tries very hard to set one up for you. The voice-acting is mostly terrible, with a special place in hell for the short snippets played during the missions.

TLDR: the gameplay is good, but beware that the difficulty can spike wildly between missions and most of the times the only solution is to farm sidemissions. Also there's a story, but who plays tower defense games for the story?

Great game!
Solid TD game witout doubt.

-Card mechanic is great. You 'waste' many hours to get a clone for your unique card to evolve it.
-Forging and evolving adds a bit depth.
-Solid gameplay, good graphics and great towers.

-Maybe a bit basic.

Love this game, and recommend it to TD enthusiasts as well as beginners. Love the art style, and the graphics.
Card mechanic is great and adds longevity, since you are constantly looking for the next great card.

Evolving and forging is a great idea, but I want to see the game expand upon it. Maybe in a sequel?
Where you can transfer random abilities (strength +10%, chance to stun 5% etc.) by sacrifying cards.

All in all, highly recommended. Get it now! :)
