Q: On the guest profile that plays along will it use the main profiles characters or will the guest have to make their own?
A:How guests can play with you on same screen co-op varies between the console systems.
On the PlayStation 3, additional players will have access to any saves that any User on the system has; however, only the primary User can unlock trophies during single-system co-op.
As an additional point of clarification, PS3 players that visit a friend's house for some local co-op action will be able to access their own characters from either a save on a USB stick, or by accessing their characters from cloud saves (if they have PlayStation Plus).
How this works is that at their friend’s house, the visiting player would need to create a new local User on the console, then sign into their Sony Entertainment Network (SEN) account with PS+ and pull down their save from cloud storage. They could alternatively bring over their save on a USB stick, but they will still need to create a new local User on the console in order to partake in local co-op with their character(s) from home.
The way this reads is that me and my son both make a character under our own profiles and play together and everything works fine. But my problem with this is two fold.
1) My son can load his profile and play on my character.
2) My son can get my hardcore character killed on his profile/game session.
This wouldn't even be a concern on the 360 since he knows better than to play on my profile.
I already preordered on PS3 but if I am understanding this correctly then I might swap to the 360 version.
Anyone with the ps3 version already confirm/deny anything?
