Prime World: Defenders combines classic tower defense gameplay with collectible card game elements. Your towers, your spells and your traps are all magical cards that you can collect and upgrade. Earning random sets of cards after each battle allows each player to create unique and exciting strategies!

Freeze, burn, poison, explode and slash countless enemies attempting to stop you from gathering artifacts from the old kingdom. 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!

I like spaceships! ,

Great game but hard to see.

I have completely finished this game and unlocked and fully upgraded all cards and did it all for free. Took a while but is possible. I really like this game a lot and have played it for years. The only gripe I have is that the text and icons are so small you can hardly see them. This is on an ipad mini and i can only imagine a phone. It didn't used to be like this. Please fix so you can have larger text and icons. I really enjoy the beautiful graphics but every thing i have to read is so tiny. Am i missing a zoom feature or something? This makes no sense. Love the game, best tower game out there, please fix so it can be 5 stars!

It’s a start

Gorgeous visuals, but the bar where the towers are is so small you can’t see what you are getting. All the writing is just SO small, and I’m playing on an iPad Air 2, can’t begin to imagine what gameplay is like on a phone. Really want to give this five stars for the graphics alone, but will not be playing until the size issues are fixed. Only played one level, so didn’t have a chance to have any other issues. At the end of the level though, the background spun around while the middle showed you how you did, that literally made me sick, you can’t do that... anyone with a tendency toward motion sickness will hurl... Good luck, can’t wait to play when issues are fixed.

Don't is practically not readable

You have to hold your phone to your face to be able to read the text, it is very very small and the zoom function does not let you zoom in far enough.

Other than the font/zoom issues this game is really great. I have not run into any other issues with this game and found it to be very enjoyable for short periods of time before I get too frustrated to continue playing because I cannot read anything. I have great eye sight too, my wife on the other hand does not and she could. It play this game due to the font size/zoom issue.
