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!

Great game, upwards of the top of nice tower defense games, however, the devs of this game abandoned it on Steam, they dumped all thier paying customers in favor of a tablet F2P version that is both updated regularly and (of course) Pay to win and full of microtransactions. So, if you want to play it, just go play it on a tablet and refuse to pay anything, the game will still be higher version even if you don't spent any money. But, on the moral side, just skip this AND the tablet version and go play the many other nice TD games. I suggest Gemcraft, Defense Grid, Ancient Planet and quite a few others. Don't support Devs like these.

Prime World Defence
Rating: 7.5/10
Overview: Isometric Tower Defence

The Good:

+ Nice Detailed Graphics

+ The game features solid tower defence mechanics. You have tower and magic cards and you can only select a handful before each level. You can collect new towers and magic by completing levels and/or purchasing them in the shop using in-game currency. If you have two or more of the same tower cards you can combine them to increase the stats which also allows you to upgrade the them in battle. You can also further increase the stats of towers and magic by using any unwanted cards and combining it with the cards you want to upgrade. All of this leads to a somewhat addicting quality of the game of completing levels and collecting tower and magic cards and making them stronger as you play.

+ Variety of different towers, enemies and levels. Typical of any tower defence game, certain towers are more useful in certain situations than others, some towers can only target land while others can only target air etc. Enemies are pretty typical as well, you have groups of easy to kill enemies, slow but hard enemies and everything in-between. Its very well done and strategy is required to make it through the level but if you've played tower defence games before nothing here should surprise you.

+ Upgrading towers and magic is very rewarding

+ Permanent passive upgrades used with in game currency to further increase stats and bonuses

The Average:

There is a story but it really isn't the main selling point of the game. It certainly doesn't take anything away from the game but it doesn't add anything to it either. You could easily skip the story and nothing of value would be lost.

I found the levels to be well done but also very standard. Compared to other tower defence games in the market it seems like a real missed opportunity to try some creative things in each level. I wish the levels got more complex in terms of enemy paths, in most of the levels you have very little control in how the enemies reach the end. In most of the levels, especially in the beginning, everything is pre-determined especially enemy paths and tower placement.

The game has some bugs but nothing that ruined the game for me

Lacks different game modes and options present in other tower defence games

The Bad:

This game requires significant grinding in order to advance. If grinding out levels is not your thing then you should avoid this game at all cost. In order to complete some of the more difficult levels you not only need better towers but you also need to level them up. The tower and magic cards you get for completing a level is randomized which means it could be awhile before you finally get the tower card you need to upgrade it. This should not be surprising once you realize there is a free version that has micro transactions to speed up the grinding process. The free version has also received a lot more updates than the steam version.


I've played a lot of tower defence games and I put in a lot of time with this one. Its very well polished but other than its upgrade system it doesn't really provide anything new to the genre. The more I played the game the more I realized just how 'safe' it was in terms of its design. The game is lacking in game modes which hurt it and the game can start getting frustrating when you reach a level that becomes way too hard to complete without grinding. Most people who are not tower defence enthusiast would probably stop playing at this point. If you love the genre than this is a game worth checking out.

I am really glad I got past my first impression of PW:D.
After a couple of maps I thought this was another hurried
TD wannabe, perhaps not as bad as Towers of Altrac, but in
an adjacent league. I was wrong.

It's true there are not many maps, and it's true there is
quite a lot of grinding involved, but that, together with a random
handicap system lets you experiment with different combination
of towers, of which there are a great many.

Upgrading your towers can be performed by joining two identical
ones or by fusing the base tower with any card available.
Card drops are well implemented* and provide a near constant
stream of new towers, spells and buffs.

This has become my go-to casual game, as due to the aforementioned
small number of maps I probably would not enjoy long sessions,
but it's perfect for a couple of rounds while you wait for your
flying monkeys to come back to your hidden refuge... or whatever
it is you do for a living.

*When the games servers are up, otherwise you do get in-game
rewards but miss the daily reward or just the increment, getting
stuck to day one. Bummer.

Having paid for the Steam version of this game feels like an EX slap in the face with a trout by a troll.

It is free to play (with microtransactions) on Kongregate, Facebook and mobile devices. The Steam version does not get updated, it's at version 1.2. The F2P versions get frequent updates and are currently version 1.7.3.

A borderline criminal business practice. On Steam, if you buy the game, they already got your money so why update the game eh ? And likewise on F2P, its of course very important to constantly update it with new things to spend money on. Disgusting.

Seriously Nival? You gave us the wonderful Homm5, and then you do this, why? :(

Its not even a bad game, its a very functional and decent looking TD with a unique CCG flavour, its actually well worth checking out. Just.. don't be a fool like me and purchase it here, play the F2P versions instead.
