Mobzombies
Read full descriptionHide full description
Mobzombies is a pixel-art, arcade style zombie game where your goal is to stay alive as long as possible before succumbing to the inevitable. Relax and enjoy chewing up zombie flesh with a chainsaw, picking them off one by one with a pistol, or sending limbs in all directions with strategically placed bombs. Mobzombies uses unique motion controls that allow you to control your character in the virtual game world by physically moving in the real world. Walk to move your character forward, turn to rotate your character. Mobzombies was an official selection of the Wired Magazine NextFest.

Verdict
The clearest difference is ads: Mobzombies at none against I.F.O!'s shown. Mobzombies also leads on update cadence (every 4 days vs every 6 weeks). I.F.O!'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price and in-app purchases there is nothing between them.
