State of Decay uses Community mechanics, which is why you are in 3rd person..you are not ONE person, you manipulate the life and story of many. You move the pawns, and control them for limited periods of time, then what you did will impact how they act when you switch. Sort of Drop-in 3rd person lol. C4 will be an MMO. Now, all that means so far (becuase Class 4 is not to be thought of as an MMO in the tradition sense), if that there will be many actual people in one world. Will each person control several survivors? Maybe, I read that the Community features will be in Class 4. That can mean you can hope from person to person OR you form a community like in SoD, except instead of AI members, actual people controlling one character make up your community. So in Class 4, 1st-3rd is possible. Not in SoD. As for looting dead survivors, you can't directly kill another survivor. Let him get eaten or blown up may work..things like that, but you can't shoot him in the face. Zombies can't be looted, but as for dead survivors that haven't turned into Zeds yet, perhaps but perhaps not because like I said, Zeds don't have loot.
