User Rating: 9.5 | Call of Duty 4: Modern Warfare PC
Even though Modern Warfare 2 just came out you need to realize they are the exact same except for the storyline and upgrades on multiplayer. The graphics are outstanding and the detail is wonderful. There are only a few minor bugs and glitches during the whole game. The AI is great too, your companions react to your actions, and even though you can not destroy the world around you, cars explode rag-doll bodies add to the realism. Plus the right amount of blood add to the effect. Multiplayer is super intense and has heart-pounding action. This game, unlike recent Call Of Duties, has a rank system. This means on multiplayer the more kill-streaks and kills you get the more ranks you earn . You can also upgrade weapons and create 5 of your own soldier classes. I haven't seen any hacks and even though you can upgrade your weapons it's not like you have no chance. Singleplayer has a good story line and is surprising but short. Overall this game kicks butt.
