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 is a great game in concept, marred by some lack of thought in the execution. I would still recommend it, doubly so if you see it on sale. Expect to get frustrated and maybe not play through it all the way, but tower defense games are usually just time-wasters anyway, right?

This is a solid tower defense game, made unique by the collectible card aspect which allows you to collect your towers as cards, and to upgrade them by sacrificing other cards. Match two of the same card and you can "evolve" a card, and thus level it up (up to a max of level 3). Burn a pile of otherwise-useless artifact cards, or some lesser cards that maybe you have too many of, and you can increase the level of your cards, making your towers do more damage and adding range. The RPG aspects people speak of are pretty minimal, in my opinion. You, as a character, do gain levels, and this allows you to buy some abilities such as larger card carrying capacity, passive buffs, and more spells/towers to pick from during a battle. There are spells which, although pretty underpowered particularly in the second half of the game, add some extra bits of strategy when your towers are ALMOST good enough. The comic-book-esque cutscenes are kindof neat, tho the story isn't exactly going to be the driving force for playing this one.

The balance is pretty well thought out, with one very glaring flaw. If you are semi-lucky and get some good rare cards early on, or maybe if you stifle your spending of stars on your stats and instead spend the stars to buy card sets, you can pound through a pretty intense game. If, however, you don't get at least a lightning or dragon tower by about the third boss, the game becomes impossibly difficult because it's balanced for actually having these top-tier cards. If you don't have the rare towers, you may find yourself doing a fair amount of grinding, which really starts to suck the fun out of the game. There are a couple 250-wave levels which are a good means of getting cards and money and experience, but you can't access these until you beat the first half of the game, which really sucks when you just need to build up to beat the last few maps. They definitely could have put more effort into making the game adapt to the cards they've let you have, rather than assuming you're just going to grind until you get them.

A couple tips for this game: if you can hold off evolving a tower card to level 3, you'll get 5% more powerful towers if you evolve four level 1 cards into two level 2 cards, then evolve those into the level 3. Takes four of the level 1 cards, which can be tedious to get for the top-tier towers, but that extra punch helps for the second half of the game. Additionally, to help combat the wunky randomness of buying a set of cards for 3 stars and finding out you wasted your valuable stars, you can go to your %appdata% folder and back up the "Prime World Defenders" folder inside it, and restore it if you get dealt a bad hand.

Solid Tower Defense game with RPG elements. Not too easy, with the ability to choose between maps of different difficulties at each point. Collecting new tower cards and forging to customize your experience. Has a "log in each day" reward, which is a bit odd, but since it's a great "few maps per day" game I don't mind.

This is one of those games you keep installed at all times and boot up whenever you feel like playing a few rounds.
