Zombie hive is a free app available on android only. It is currently not available on itunes. The game itself has a zombie theme to it, but its basically a building game. The whole game revolves around you digging your way lower into the ground building more levels.
The positives to this game are that it has a pretty easy learning curve. It will literally only take you about a minute or two to get the hang of things in zombie hive. The problem with this game is that it can be pretty repetitive. After youve played it for about 20 minutes you might be done with it. We still recommend checking zombie hive out since its a free app and a decent builder.
