Call of duty modern Warfare2
a game i waited so much for it but it let me down so bad .
short campaign,Stupid story,Some nice missions,Stupid Perks&killstreaks ,Cool Spec ops And Good Acheivements were some of the things i saw in this game.
i played it on easy 1st time its so easy a baby can win it !it finishes in 3 hours!
i played it on veteran for acheivements it was so hard that i cant even describe it!
the AI is cheating like hell.
they shoot towards you before they see u and whenever they don't guess what?
GREN@DES!!!!!!
the AI pissed me off more than anything in this game.
after that the juggernaut was frustrating in some spec ops levels like high explosives!
they shoot at u even when they dont know where you are.
and then the Helo from the oil rig level that doesnt die like other helos .
well i am waiting to see if Black ops has anything to say after this scandal!!!!!!!!!!
