I'm happy somebody picked up on the subtle G.I. Joe reference. I haven't found any reviews from the regular video game sites, but the game is getting slammed hard by user reviews for some reason. If nothing else, their commercial kicked ass!
Black Ops 2 has different endings depending on your decisions through our the game. So when you play it again... Change it up a bit.
Multiplayer has less lag than MW3. I'm liking free for all. When I play domination or kill confirmed, it lags from time to time. Be sure that you change the connection type in the multiplayer settings to BEST. It will take you a bit longer to find a game lobby, but you will avoid aggravation when your bullets don't kill anyone. So... Learn from my fail.
