Mass Effect 3 is one of the biggest — not to mention most controversial — games in recent memory, and if you somehow missed out on the mission to save Earth, Amazon has a deal for you. As part of its latest Gold Box promotion, Amazon is offering Mass Effect 3 for $29.99, a 50 percent drop from its normal price tag. The deal is on for the rest of today and covers the Xbox 360, PlayStation 3, and PC versions of the game. There's also a series of lightning deals that will be available for short windows throughout the day, with the first being a Turtle Beach Ear Force X32 headset for $64.99, but the later deals are still unknown — so you'll have to keep checking back here to see whether any of the sales look tempting.
