Some time ago, Chuck Bittner posted a petition
appealing to game developers to include an option to allow gamers remap their button configurations. This may not seem like a huge issue generally, but Chuck Bittner is a disabled gamer who has difficulty reaching all the buttons on some game controllers, so remapping is key to his ability to enjoy many titles. Besides, who amongst hasn't played a game and found frustration because the default controls just didn't seem to make sense? I don't know about the rest of you, but the lack of y-axis inversion in Silent Hill Homecoming
made the game almost unplayable for me at times.
The folks at Valve have apparently taken Chuck's petition, which has presently collected over 74,000 signatures, to heart, and, as per an email to Mr. Bittner from Jeep Barnet of Valve, the developer will be introducing button remapping to http://www.trueachievements.com/Portal-2-xbox-360.htm
along with the upcoming free DLC
which will be released this Summer.
Both button remapping and horizontal inversion will be available once the new DLC arrives.
