So theirs a new game in alpha right now that is a spin off of the very popular Day Z called War Z .... go figure haha. I payed the $30.00 to get into alpha and coming from someone who put in about 100-150 hours on Day Z im happy to say this game steam rolls it. Considering it is in alpha this game I think will be the successor to Day Z. From the way your guy walks compared to Arma 2, the way the game is setup, strongholds for items and many many tiny things just make this that much better. I could list probably 50 things but it would turn this into a short forum post into a TLDR real quick.
All I am saying is I suggest you guys to try it out. I think it is only 30$ still but theres a bunch of different ones you can buy depending if you want to wait for beta or if you want to rush into alpha along with packages that offer a private server for 6 months post release. This is going to be the League of legends to Dota, a good mod gone better by a small company. Well worth the $
