The first ArmA II developer diary that was released two weeks ago was nine minutes long and this second one, clocking in at almost eight, is nothing to scoff at either. This time the diary focuses on the editor and shows how players can create their own missions and change anything from simple waypoints to AI behavior. It focuses on the simple stuff but those who are sick of the game’s own missions and have a little creative bone in them can apparently whip up something quite impressive as the game allows players to put together full blown campaigns with cut scenes and all that fancy stuff.

ArmA II is out now.
