All you have to do is make a separate save file for two different profiles. There's not really any profile slots for multiple accounts.
At the moment no.
no
If the two profiles are different saves, they should indeed be able to work on a single profile.
u can have as many as you want just make sure your 360 or ps3 haves enough memory to save there will be a certain number though u wont maybe cant do as many as u want maybe 10 or 20?? dependsss...
you must type in between for a space and for two spaces
you can make up two six heroes or villains
you get two profiles on and then go to campaign on coop
No, you can only have one.
nope
if you want to make another profile just start a new game and save it in a different save slot you can have as many as you want.
On Split-Screen Multiplayer you can use 2 different online accounts but only on Xbox 360. On PS3 the second player must play as a guest meaning all unlocks and ranking is reset after signing out.
not at once.
