Now that I read it again, the gamepad features mostly giving easier/alternative methods of control. The only one that adds new mechanic is the grenade throw-back.
Looks like there's a chance for a patch then
it might also be in DLC form too considering the extra missions (tong's rescue mission + missing link). The changes are mostly tweaks, so even if it's a DLC, it should be free I guess...
Yeah, I almost never use typhoon in the game, though
