Below is the manual and a quick rundown on the basic controls of Resident Evil 6 for the Xbox 360. Since the game doesn't come with a manual and some functions are just not explained well in the game, I've gone ahead and include the manual to make your little easier in when playing the game. It'll cover agent hunt mode, accessing your inventory, run down on fighting controls, etc. Most of the basic questions you'll encounter will be found in the manual below. Sadly, I had to go looking for it one point so here it is case you guys find yourself in the boat I was. IGN managed to get a pdf copy of the quick start guide online and the official one is below as well through CAPCOM Unity website. The official copy below is for the PS3 and Xbox 360.
