Spend $1.5 on Groupees and get a Bundle of The Undead
Groupees is currently making an offer for a number of games. By simply spending $1.50, you get to download 2 games of your choice. You can download more if you are willing to spend more. One of the recommended games in the list is the Undead and Zombie gore. You might also want to consider Necrovision but keep in mind that the game has been banned in Australia. That been said, you should be able to get a censored version available. Another game you might want to consider is the Haunted. This one too is a little bit violent but it is OK in comparison
