This is the absolute worst COD multiplayer considering games are supposed to build upon themselves and get better. Single respawn locations, garbage map design, and killstreaks are just the tip of the iceberg in this epic failure.
If someone is rating the multiplayer in this game highly it is solely because they are one of the countless number of people with absolutely no skill who exploit the terrible designs of the multiplayer to sit and spawn or objective camp. I can not overstate the serious level of camping I have experienced in multiplayer.. 100/100 will never play multiplayer on this again. It is not even close to fun to play if you are a real aggressive gamer who likes to run and gun.
I am guessing most of the high ratings are for the campaign which has well done graphics, a weird but interesting storyline, and descent gameplay. However you can and should beat the full multiplayer in a matter of a few hours. It is incredibly short. Word to the wise SAVE YOUR MONEY! Buy this game when it costs like $20 somewhere in the future get you 5-7 hours of solo gameplay out of it and move on.
