"Oh, man -- it was so awesome. First multiplayer match I get into, and I get like, a 200 kill streak. It was in this weird airport lobby level, and everyone else must have had really bad lag or something, because they didn't move much -- but still! It was the coolest thing I've ever done, and I didn't get a Trophy for it. WTF?"
While we're not certain Trophies are distributed for ... the feat mentioned above, it does seem that the PS3 version of Modern Warfare 2 is experiencing some trouble rewarding Trophies to its players. The problem seems to be with a pre-launch patch which, for some reason or other, disables the game's unlockable incentives. A fix for the issue has been discovered by a few fan sites, but we've contacted Infinity Ward to see when we can expect a more official solution to surface.
