Easy "Couch party" Achievement...
	Various Trophies...

A total of four controllers are required. Start soloing any tomb, except for the small challenge tombs. Before reaching the end of the tomb, open the menu and change the game type to a 4-player local game, then select "Continue". This will allow the other controllers to choose a character to load at the last checkpoint. Get at least one character to the end, allowing the others to die if desired. Note: You may need to control two characters at a time to end some levels.
