Call of duty 4: modern warfare

Call of duty 4: modern warfare(here-and-after represent by "cof4") is the most interesting of FPS(first person shooter)game, unbelivable graphic quality output by small 3D engine, total file size are 4.7G, compare to AREA 51, 11G, it is a huge different in size, although the quality of 3D affect are similar. Cof4 are fabricate story line based the Middle East conflict today. The game 3D engine was successful simulate the scene of real war, including the morden war tactic, use of chopper, lightning attack, secure enermy commander by catch alive, nuclear explosion, assassinate the head of a terrorist, us marine, sas, and more and more modern interest. It is totaly different feel with the previous project, i had play cof4 more then 5 times, and i still feel interesting. I heard cof5 are coming soon on end of year 2008, it will bring back the stroy background to WW2, on pacific war, againts japan army, i think it will be more fun:D
