Moncho: The games are too different to compare. CoD is more of a fast paced game while battlefield is more oriented towards long battles.

Dagger: They're building a brand new engine, along with adding features like we've never seen before. If I've understood correctly thus far, I believe there will be an exo-suit on every character that allows for super-human strength, including jumping and running. I'm hoping all the new changes will be for the better, since it's SledgeHammer's first CoD release. Glad they're finally changing up the series a bit either way.

-Link: Infected is quite fun to joke around in with friends. I'd probably say my favorite new gamemode is Blitz. I think it's much more competitive than CTF was in the other games, as it doesn't require you to slay the whole team and then pull a flag back to your base. There are a lot of sneaky plays that can be made, like waiting around a corner and letting a few enemies walk by without killing them so they think that no one is behind them, then run in for the sneaky score. It can be quite fun.
