Choose your cards carefully and play them strategically - there will be heavy resistance along the way. Battle everything from small mutated fungi to powerful giant goblins and nagas!

In addition to the story-driven single-player campaign in Prime World: Defenders, each players’ experience is unique thanks to custom generated missions!

IAP's don't ruin it

This the ONLY game I know with IAP's where they are not required. You don't have to pay to win. You don't have to wait to continue playing. (Have game publishers forgotten we all have a family, a job and school?) I have enjoyed this game gradually over many many months. The progression and balance is amazing. Whenever I get stuck I just mix it up and try new towers and combinations. Now I believe am on the last level! A quality, superbly crafted game and I salute the developers. Thank you for not being greedy IAP publishers! I prefer to pay once and play, even over ads.

Great so far

I'm playing on an iPad Air 2 and have had no problems. No bugs, no crashes. The game is truly gorgeous. I really like TD style games, there are a lot of them out there but I haven't been this excited about playing one since Field Runners and Sentinel. Defenders seems above and beyond so far. There's depth, a decent story, terrific graphics. A lot of folks don't like the in-app-purchases. I haven't spent any money yet. I'll have to wait and see if it becomes too hard without paying. I don't mind spending a little in support of a good game. That's how it ought to be.

Unbalanced game that forces you to spend money

There are so many issues with this game that I don't know where to begin. Too bad because this has the potential to be a really good TD game but, the Devs are plain greedy. And, please don't give me the lame excuse that they need to feed their families. They could have charged upfront for the game rather than being deceitful in trying to pry money from us.
Let me just warn you that even when you do get so frustrated with the gameplay that you spend money to get ahead:
You will think you're buying a specific card but will be given a different one.
Even after hours of grinding and spending money to get the best towers, the game is so unbalanced that you will be easily overwhelmed by hordes of enemies
