So you've probably heard of Arma II, no? Well, then I'm sure you've heard of Day Z. If not, Day Z is a zombie survival game that was originally a mod for Arma II. Like many popular mods, they often outsell the game it originates from. This of course grabs a lot of attention from developers and publishers that would like to help launch a full standalone version of that mod. However, it also grabs the attention of potential copycats.
Not only that, items and food are not found, they're bought with real cash. A freemium system, in a game that's not free. This guy has outdone himself.
