Unlock all characters : Save files? Cheats that work?

[GenericHenchman]

Has anyone figured out how to unlock all characters without disabling the save system? I've even looked around online for a save file with all characters unlocked, no luck! I want to play as Venom, but you get him at the end...

Only Thor, Jean & Hulk can, one by one via cheat codes available:

BTW, I recommended to unlock Gallery related cheat codes outside Gameplay, as in on Main Menu only, then you’ll be able to save game on your gameplay

I know this is old but i wanted to revisit this. Because I have a ng save on PS4 with all characters unlocked. I can’t remember how i did it. I think it has something to do with co-op.
