MGS3.
Roto decided, that if I'm not stealth killing, I can use the knife. So only when I'm in alert, or for hunting when there's no enemies (beings I only have so many cages.)

I've already killed 10 guys. I'm whoring the down loadable Grenade Camo. Infinite grenades. Also, the down loadable mummy camo, as it prevents bleeding. Died twice on my way to Sokolov. But then I got the shotgun. I was just ambushed by the boss (in Snake Eater, not Virtuous).
