As with previous bundles, purchasers get to name the price to pay; paying more than the average unlocks additional items, and paying past a certain amount unlocks still more stuff. As of this writing, it’s going to set you back about $10 to get a whole bunch of stuff for your online game of choice. If that sounds like a bargain to you, head on over and buy yourself a bundle. Heck, you could even forget that it grants you a digital ticket to E3 along with all of the games.
