Wow!!!!
They also set up an online ranking mode which keeps you hooked to go onto the next rank, also the system of unlocking attachments and newer guns has been very well set up and the "Prestige" modes are really exciting.
The single player mode is an entity in itself aswell with as great a storyline you can possibly have with a FPS. But the only knocks on this game are that it has a couple glitches on a few maps and the storyline comes up a bit short in length, and as PS3 owners we may have come up on the short end of infinity wards favourites list because the leaderboards are poorly done in comparison to the 360 version. Disappointing but hopefully they can provide an update to fix that.
But overall that doesn't take away from its shine of being the greatest FPS to date.
The only other thing is the fact that they could come with more maps as it does get repetitive playing at certain areas.
