DayZ might be the talk of the PC gaming town at the moment, but for all its qualities at the end of the day it's still just a mod. It's using the engine and effects from ArmA II, which play a big part in helping the game achieve its brooding atmosphere.
Thing is, ArmA II came out years ago. Its sequel, ArmA III, is on the way, and for a sandbox game set on a large open world, it looks amazing.
We'll be checking out the game in person at E3 next month. Cannot. Wait.
