I was looking on eBay for Halo 2 mods and I came across this cool mod with 2 buttons on the back of the wireless 360 controller, which function as A & B. This makes it so you can jump and melee without taking your thumb off of the thumbstick. Pretty cool! I've already ordered one and hope to see it soon. Check it out. http://cgi6.ebay.com/ws/ebayISAPI.dll?ViewListedItemsLinkButtons&userid=halo3controllers
