Red Dead Redemption, one of the biggest selling games of 2010, is going crazy with XP. Normal developers would usually give you a weekend or so of double XP, but Rockstar could never fall in the normal category, so they decided to give everyone double XP from now until the 3rd of January. That’s 2011 folks. This double XP week will be available on both the Xbox 360 and PS3. Go shoot a horse kids, in-game of course.
