Fallout New Vegas (Xbox 360, PS3, PC) for $19.99, Used (Xbox 360, PS3) for $15.11

Feel the Heat in New Vegas! Not even nuclear fallout could slow the hustle of Sin City. Explore the vast expanses of the desert wastelands - from the small towns dotting the Mojave Wasteland to the bright lights of the New Vegas strip. See the Great Southwest as could only be imagined in Fallout.
Feuding Factions, Colorful Characters and a Host of Hostiles! A war is brewing between rival factions with consequences that will change the lives of all the inhabitants of New Vegas. The choices you make will bring you into contact with countless characters, creatures, allies, and foes, and determine the final explosive outcome of this epic power struggle.
New Systems! Enjoy new additions to Fallout: New Vegas such as a Companion Wheel that streamlines directing your companions, a Reputation System that tracks the consequences of your actions, and the aptly titled Hardcore Mode to separate the meek from the mighty. Special melee combat moves have been added to bring new meaning to the phrase "up close and personal". Use V.A.T.S. to pause time in combat, target specific enemy body parts and queue up attacks, or get right to the action using the finely-tuned real-time combat mechanics.
