Metal Gear Solid 4: Guns of the Patriots
If you fight Mantis with a Sixaxis controller, the ending is different than if you were using a DualShock 3 controller.
In Act 4, kill one of the wolves after you defeat Crying Wolf. The others attack you. Call Otacon and he will wince. Call Rose and she will tell you that animal cruelty is the first sign of criminal behavior, and says that she will have you psychologically assessed if you continue to kill them.
Complete the single-player mode once (and saving the cleared data).
After dying, call Rose to get a conversation about Snake having dreams of being killed or a comment from Snake saying that he feels like he’s died once before.
