This was requested by @Nardaq_NL. It should work on any MiA server:
In ut2004\user.ini section [Engine.Input] on a spare key, (in this example the "Y" key)
Y=UseCombo FFFF
In-game the "Y" key will now trigger the speed combo if you have enough adrenaline.
Combo's
F = move forward, B = move back, L = strafe left, R =strafe right
FFFF : Speed
BBBB : Booster
FFBB : Berserk
BBFF : Poo Combo (if on map) / Resurrect (Freon, where you can also use "UseNecro" bound to a key )
I'm not sure we use these ones:
RRLL : Invisibility
LLLL : Pint Sized
RRRR : Camouflage
