"The sound and graphics in Doom 3: Resurrection of Evil are entirely the same from Doom 3 on Xbox, but the gameplay has been tweaked to make it more fun and interesting. As a result, if you enjoyed Doom 3 on Xbox, it’s safe to say that this expansion should keep you happy as well.

Resurrection of Evil makes much better use of Doom 3’s physics engine than the first game, with boxes, chairs and even chunks of walls fluttering and falling about. I wouldn’t rate it as highly as the Havok engine used in other games, but it does run a close comparison. The physics, much like in Half-Life 2, have freed the developers to implement some cool gameplay tweaks, including a gravity gun called the Grabber. At first it just feels like a cheap rip-off slapped on there to say “Me too!” but after making your way deeper into the game, you’ll find it invaluable to your survey and a whole lot of fun."
