I would like to know if there are controller options other than default. Like southpaw or southpaw legacy .

There are presets along with custom remapping on both PC and Console

Here's a list of the pre-set controls schemes in "Brink":

"DUTY CALLS" = Call of Duty Controller layout
"GREEN MARINE CHIEF" = Halo Controller layout
"ZONE OF KILLING" = Killzone Controller layout
"OH MY GEARS" = Gears of War Controller layout
"FIELD OF BATTLE" = Battlefield Controller layout
"ZOMBIE KILLER" = Left 4 Dead Controller layout

I strongly suggest reading H0RSE'S Compendium, read through that and if you still have questions ask here then!

yeah i heard they were making it were u can set up how u want your controls like on cpu. and theres five other types like halo controls killzone call of duty l4d battlefield
