A BioWare representative announced on the developer's forums (login required) that one of the most ambiguous, open-to-interpretation game updates we've ever encountered launched this morning for the Xbox 360 version of Mass Effect 2. Sure, a few of the changes included in the patch are straightforward, such as a fix for a game-crashing error that would occur due to DLC incompatibility and the removal of another glitch that would allow the game's more sinister players to get infinite skill points using a simple menu exploit.

However, some changes are far more enigmatic -- particularly the suggestion that "scanning for minerals has been optimized." What does that even mean? Is the mining minigame now faster? Do you get more minerals with each probe? Can we now listen to phat beats while performing this otherwise mind-numbing task? We'll just have to download the patch to find out.

Check out the full list of (frequently perplexing) changes after the jump.
