For everyone going for the achievements, heed this advice;
The achievements for playing all game variants and all maps can be achieved very quickly, if the host ends the game as soon as it begins.
You get 2 options; Quit Game and End Game. If you end the game, you'll go back to the lobby where you can choose the next map and variant, and load it straight up. If you keep pressing A during the count down, it'll speed it up.
If you do it this way, it'll take about 30 minutes at the most to get those out of the way, and then you just need to pick a map with the correct weapons and vehicles to get the rest. I picked the large one with the Banshee, Warthog, Sniper, and Rocket Launcher.
EDIT: Another tip. If you press F1 (IIRC) on your keyboard, you can use in-game chat, so if you don't have a headset, you can still communicate very well. The keyboard still functions when using the 360 controller.
