I just played through the Demo for Call of Duty 2, and I have to say, I’m really impressed. They decided to make their own graphics engine, using of using the hacked up Quake 3 engine that powered the original Call of Duty. It looks really good, but also runs surprisingly well on my computer. The combat was just as engrossing as the original Call of Duty, but they really picked it up in terms of the atmosphere; That was one of the best things about the original Call of Duty, and it’s even more intense in the sequel. If you liked the original then I suggest you go and download the demo for the sequel.
I’m looking forward to playing through the single player, but mainly I anticipate the multiplayer. Call of Duty has the most enjoable multiplayer of any FPS I think think of, except for maybe Halo; and even that’s contingent on being in a room full of friends.
