an awesome single player campaign, if alittle shot, and acording to a few reviews i've seen amoung the best multiplayer stuff for an fps. haven't tried it yet as still doing the single player bit, then will prolly do it again in the hardest setting..
Theres a class system for the multiplayer, and various advantages u can pick as the get xp, shitload of weapons and with enough xp can call in air strikes 'n stuff
graphics+cinimatics of the campaign are great, with sooo many situations. it rly does pack alot in considering its not that long.. hectic warzones, stealthing about, tank/plane/copter gunman, ambushes, deffense, assult, search+rescue, assasinating nasties and claymoooooores!
i recomend it..
