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!

Only just started playing but loving the graphics and the story. Best graphics on a phone game that I have seen. Granted it’s kinda hard to see some writing on the tiny screen but it’s worth it

Thank you for writing a review and good luck in battles!

Really good

Great graphics, great gameplay. The distinguishing feature of this t.d. Is the back end. You get to construct upgrades for your towers which is a lot of fun. There's quite a bit of innovation here, but not so much that it would put off dedicated tower defense players. This is one of the most fun games I have played on iPad in a long time

don't bother

don't bother watching the mini films to double down your silver/xp wins, you watch the film and then the game crashes and you don't get the double down

effectively making you watch the adverts with no rewards, time consuming so as to progress twice as slow

the game crashes regularly even without the mini films

other than that it's a great TD, solid graphics and storyline, good towers that fit well and synch well, challenging without being too hard

add an endless mode for each map with a tower/hammer to remove blockrocks

add an option in the fusing and evolution screens to NOT see the towers already max'd out

iPhone 4s with up to date iOS
