I think gears 2 should have more single player achievements besides chapter completions. My other idea is that multiplayer achievements could count campaign kills too. (So like the achievement could be "1000 kills with the shotgun" so multiplayer kills could count like 2 points and single player kills would count 1 point, sinse AI kills are easier to get. or higher difficulty could count more... i dunno im just thinking out loud, tell me what you think.
there are a ton of threads on this. but i agree i like the single player achievements better...
by the way this is the wrong section of the forum for this kind of thread. Put this one in general chat next time.
