"There are different endings you get in Manhunt 2 - and what ending you get depends solely on your playstyle. The word "playstyle" referring to the question of whether you slashed, sawed, tore, and plastic-bagged every victim you could get a hold of in the game, or simply chose to do it Solid Snake style and killed only when necessary.
But it's not just the endings, however. Playing with a violent streak - that is, testing out every weapon you get or succumbing to every opportunity for an environmental kill - would get you not only a gloomier ending, but a darker, grittier final stage to precede that ending. Taking the stealthier, less bloody path would get you a lighter final level and a somewhat more positive ending.
Certainly good news for those of us who'd like to spill as little digitized blood as possible in our games. No word yet, though, on which ending would be canon, or if the endings themselves will see the light of day come the title's release (whenever that may be)."
