Call of mini zombies mod APK is a free-to-play game, but you can relax in some aspects by having some in-game resources that can be purchased with real-life money. If your device is rooted, there is no need to pay for this game because mods will do all of the work for you. Apart from the campaign mode, there are two other modes to play in this game: single and multiplayer, and zombie mania, in which you must survive on a small island, fight off zombies, and complete your objective by collecting items.
