“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…”
“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 The steam version is outdated.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…”
“Servers are offline so you cant play anymore. It was great game but got ruined by useless always online features. Its like watching Ubisoft game in small scale.”

“84 / 100 Tower Defense crossed with a Card Collecting game; an unusual mix that strangely works well together. You have a set campaign of around 20 quests to complete before you, with some side quests you can do between…”
“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…”
“One of the best tower defense games in steam at the moment. Top graphics for the genre, good mechanics and twists, it has an interesting story and lots and lots of towers (and upgrades). You use cards to defeeat the…”

“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…”
“A good TD game which suffer from bad porting and an intense grind. https://steamcommunity.com/sharedfiles/filedetails/?id=1433712683 I liked the game at the beginning. There is a nice story with cool comics. The…”
“No no no no. It's a promising TD game. Good graphic, decent mechanics (using card system to deploy tower and it has even magic and talent trees) but the game is not even supported. You'll see your screen freezes every…”

“Really good Tower Defense game, recomended for anyone that likes TD games or even card games as the mechanics are card based. A bit of grinding may be needed at some points but the random generation of totems on maps…”
“Very fun and adicting game. I love the upgrade system, the rare towers, the unique towers, are awesome once fully upgraded. Though you have to do alot of map grinding to be able to progress further into the game, the…”
“The most important thing about a game is 'is it fun?' All of the warts don't really matter if you're smiling a bit as you play. Prime World: Defenders is fun, especially if you like tower defense games (TD). The UI is…”

“A decent tower defense, with some interesting gameplay elements like card upgrades. Bosses require special tactical thinking. Gets kinda boring towards the end. Warning! Very buggy achievements (even with the latest…”
“This game is fantastic! The best part is waiting to get the right cards. But also the very near wins, the surprise when you finally clear a board that was previously impossible, the slow progression building up tower…”
“70 hours in and 4 achiefments left to get about time to write a review i thought this one hooked me from the start i love the cradting system it has, when i first started i played too far too fast so i ended up…”

“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…”
— a player, Steam review · 76 hrs played“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…”

I -LOVE- tower defense games, to the point of friends making fun of me for playing anything in the genre now matter how bad it looks. I picked this one up on a whim and right off the bat I could…”
