UNKILLED - Zombie Online FPS App Reviews

I thought the game sucked but I really love the game.

Can you put normal and hard for campaign? I kinda like the game more than dead trigger 2 but the only thing missing is difficulty.

When ever I have someone raiding my base, I do it. But some times the game crashes, so then I get back to the game, and look we have here, the moron raided my base because my game crash! Please change this, it is really annoying!
