Some users need to bind the boost or dodge to single keys for gamepads or joysticks. It's possible to rebind these actions to single keys but only via editing the config files. Credit goes to shosca for posting it on the former forums:
I've done it. Disabled shift+s and mapped x to quick 180.
Search for GBA_Backward in HawkenInput.ini file and you should find lines that start with:
Bindings=(Name="S",Command="GBA_Backward" .....
Make sure this line has bIgnoreShift=True, if its missing add it like:
Bindings=(Name="S",Command="GBA_Backward",bIgnoreShift=True)
if it is set to False make it True.
Now create a copy of this line right there and replace "S" with "X" and replace Command with "GBA_Boost | GBA_Backward". This will bind X to quick 180 without shift. Make sure there are no other lines that start with:
Bindings=(Name="X"... within the config section.
You can also bind left and right dodges like this to individual keys if you want to.
