I have played the COD5 full game and the campaign is shorter than most of the Call of duty series but Its still fun with up to 4 player online co-op, Also a new fun feature Nazi Zombies try to survive hordes of Undead in your small little fort get weapons like M1garand or Browning, m2 flamethrower, or my favorite a ray gun pistol that kills zombies in one hit. Online play with more than 5 maps is very fun no lame Helicopters that kill you in buildings or airstrikes that go at the wrong angle over all I give it 5 stars definitely worth it,
