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.

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.

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.

It is a fun TD. However do not buy this game. There is a free version out there that is better. The steam version is outdated. In addition after a while the game just gets repetative and there is a ton of grinding you need to do to progress

Adding grind to tower defense is like adding salt to the sea. It already has too much and the end result is crusty.

Metascore 58?! Are you kidding me? I just don't get it. My only complaint with this game is that it's too grindy at certain points, and with not so many maps it can make the experience somewhat repetitive. Aside from that, the upgradeable trading cards meets tower defense idea here works surprisingly well, and above all it's fun. If you're a fan of tower defense, I say go for it. It's one of the best in the genre (up there with defense grid, plants vs. zombies, etc.). 8/10

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.)

This game feels suspiciously like a mobile IAP-based game that was translated to PC...

First though, the good -- the game looks very nice indeed for a tower defense game. Very high production values when it comes to visuals and overall presentation.

But back to the mobile app part -- unlike your typical tower defense game, which focuses on strategy and proper tower placement / usage, this one features a very heavy emphasis on grinding for permanent upgrades to your towers, which makes it almost as much of a hybrid RPG game as a traditional TD one. The game features a booster / upgrade store, and it is this part which feels distinctly like a remnant of a mobile port. As the levels progress, the same types of creeps gain increasing amounts of health, while the strength of your towers remains constant - thus the need to spend substantial amounts of time grinding previous levels for money to buy upgrades. One might imagine that a mobile version of this game would include the ability to buy these upgrades on the spot in exchange for real money...

I'm kind of ambivalent about whether or not to recommend this game. The hybrid TD-RPG concept can work well and be enjoyable, but in this case, I think my problem is mostly with the balance and unnecessarily high grind requirement.

Not a bad game if you like tower defense things. However (and this is a big however) it appears to be abandonware now, while the free versions still get updates. That wouldn't be terrible, but the game has broken achievements, VERY few maps, and "upgrades" that appear to do absolutely nothing in the paid version.

I am slightly conflicted in recommending this. On one hand, purely from a "tower defense" perspective, the gameplay is pretty solid. Everything works as it should and it is well-designed (nice interface, towers all serve specific purposes, enemy health, waves and routes are clearly indicated, etc). And most importantly, the actual gameplay itself is fun. What brings this down are the nonstandard elements the developers tried to introduce into the standard tower defense formula - specifically, the "card system" (and everything that comes along with it). There's nothing wrong with the basic idea - tower types are represented by cards that can be collected and leveled up, and you have to pick and choose a subset of cards from your deck before going into a level. Where the problem comes in is obtaining the cards you need you be successful and "leveling up" those cards. First of all, the leveling system is overly confusing and needlessly complicated. Secondly, in order to beat the later levels, you will need specific cards leveled up to adequate levels of strength. The problem with this is that most of the cards you get as rewards are random, so you could go a good long while without (or possibly even never) finding a Lightning Tower card, for example (which I would consider absolutely essential for beating the game). And even if you are lucky enough to get some good towers, the process of leveling them up takes serious time. You basically just need to keep grinding out optional levels to get extra cards that can be used to fuse/evolve other cards. And make no mistake, you are going to be doing some serious grinding. So, depending on your tolerance for grinding levels and ranking up things, that's how I would recommend you make your decision to buy this or not. Personally, I am the OCD-type who feels the need to level things up and complete stuff, so I forced myself through and eventually got enough cards of high enough strength to power through the main game, as well as the extra hard difficultly that unlocks afterwards. While I did enjoy the game overall, it did take a lot of time and effort to get the most out of it. To me, tower defense shouldn't be about making towers strong enough to win by brute force. It should be about overcoming the challenges using a set of predefined towers and nothing else except whatever strategy you come up with. The first half of this game can be played along those lines, but once you get to the later levels, you will absolutely hit a wall if you don't have certain cards leveled up to a certain strength. That's poor design in my eyes. But even with all that said, I honestly still had fun with this game, as it's well made and I have a semi-high tolerance for grindy things. If you think you can deal with the grinding issue and like TD games, definitely go for it. Otherwise, you may want to hold off or wait for a huge discount.

Yet another dead game on steam.

It was a good tower defense game until the Devs shut down the servers which means no steam achievements no stats no more updates.

Some people have lost progress, all the above seemed to happen after releasing the devs Prime World Defenders 2 on the mobile.

I would have said get this game before no get gemcraft or any other game which still works.

Interesting game, but sadly, since the Developers killed the PC servers, you can't never connect or get achievements on your steam account. Since, personally, this is a major issue to me - mainly being completly abandoned leaving part of the game broken, and no way to get achievements do to they own fault - I'm leaving a negative review.

If the developers can't be bothered to have the server up, or at least make an update so it connects directly to steam, plus not upgrading the game but keep the game in mobile getting updates from time to time, then I can't be bothered to play the game nor give it a positive review.

Ps.: Wouldn't buy the game if I knew this was an issue, and I'm sad that I did.

It is currently impossible to earn steam achievements in this game, as the devs have appeared to take the servers offline (been that way for a few weeks now). Also, the store daily specials do not update, and there is no daily login reward.

I will update this review should the developers change this, but as of this moment, that is a gamebreaking bug for me, and I'd never be willing to put my word behind a broken game.

Please mark as helpful so that others can see before buying.

Prime World Defenders is a good game in it's base but is unfortunately crippled by it's progression system making it an absolutely unrewarding grind to play.

When completing a mission (the first time) or playing one of the "random" side mission you are rewarded an item card, this can be a tower, a spell, an item that is a tad better for upgrading, or one of the game's currencies.
The issue with this system is that you getting the cards you need is completely random, so you can find yourself in a situation that you do just not have the cards you need. And even when you get the card you need, it will be so underpowered in comparison to the cards you started upgrading that they are pretty much obsolete. Speaking of obsolete, some towers even when fully upgraded get straight up outclassed by the "rarer" ones, that is after you started upgrading those repeating the cycle.
It's a horrible system that turns the game from enjoyable to frustrating.

Unfortunately that is not the only issue the game has. The magic system for example (again cards you need to upgrade) is completely useless since the spells do not scale with the waves, hardly making a dent some waves in.

There also is the issue that there are no fine controls in the game for the towers, you can not set a tower to attack the enemy the furthest along, or maybe the weakest. This adds another layer of frustration especially with the boss fights where towers tend to lock on to the boss and les all the weaker minions pass.

It is a shame really, the base game is good and with some minor tweaks it could have been darn solid. But do yourself a favour and don't loose yourself in this frustrating mess.
