yeah, CoD is THE ADD multiplayer game. Reach seems like it is trying to become a bit faster with abilities, but it is still considerably slower than CoD.
Outside of Hardcore, CoD has like no respawn time, you can run around the map dual wielding shotguns, throw knives, etc. all while numbers pop up making you feel good about shooting an enemy as they fell for the 5th time. It's really fun for it.
One thing I haven't read was if they were downplaying the importance of vehicles in multiplayer. Reading the coverage and from the two games I playd last night, there aren't vehicles except in that one Spartan vs Elite mode.
