Here's the deal – Z Buster Review

The game is relatively enjoyable, as silly zombie shooters go. Watching the zombies dance to Michael Jackson music or dance gandum style before getting shot or blown up is worth the download since it hilarious! Graphics are clean and animation is smooth. The problem is the cost for the in app purchases and the battery drain. It appears the game has a memory leak or others bug. It drains my fully charged battery down to about 46 percent after 15 minutes of gameplay. If the developer fix the bugs and moderate the IAP cost, this would be a keeper.
