Promo says there is a persistent environment, which I take to mean that there's only one map. You run out and find crap and other people try to kill you, at which time you lose said crap. You only get to keep the crap if you run back to a specific point. Sounds boring as crap to me. I'm solo PvE. I'm not buying a new console to play it so it matters not to me what it's actually going to be like in reality.
