Not a very comprehensive trophy list, no trophies for things like playing the entire game without an alert, or playing the entire game without killing anybody (which you get special bandanas for on subsequent replays). Seems the trophies were implemented on a half-assed level. Shame, but I will likely still play it again to get a few more trophies. Been wanting to replay MGS4 for a while now.
In order to get the corpse camo, you have to get the Big Boss emblem (Extreme with no alerts, under five hours, no kill). In all honesty, it makes that single silver harder to get than 99% of the other ones there. The only harder one is the platinum which is getting all of the trophies..
never been a fan of trophies. there's only a few games i'd play to get trophies, just to see if i'm good enough, otherwise, i prefer personal achievements and playing people i know to see who can brag.
