Fallout: New Vegas Achievements and Trophies

General information
The PC version of Fallout: New Vegas will use Steamworks for achievements, and the Xbox 360 version will use Xbox LIVE. Unlike Fallout 3, the retail PS3 version will ship with PSN trophy support.

Please note that cheating, on the PC version at least, appears to disable achievements for that play. If you are cheating (or using console commands to get around bugs), you won't get any achievements unless you save, quit, reload, and redo the achievement.
