Installation:
Place the two included folders in "My Documents->Unreal Tournament 3->UTGame".

Custom Controls:
For the control input, Epic uses a scheme that links a button name (Example: "Q") with a GBA_xxxxxxxx (Example: "GBA_ToggleTranslocator").  By overriding the functions that the GBA_xxxx call for Unreal Demolition ONLY, I Can achieve custom controls without wrecking the player's control scheme.  In order to customize your controls, change the fields immediately following the header [UnrealDemolition2.UDPlayerInput] in UTUnrealDemolition2.ini.  The defaults for the configurable fields are seen below.

Default Custom Controls

BarrelRollLeft  = Toggle Translocator
BarrelRollRight = Use
FrontFlip       = Switch To Best Weapon
BackFlip        = Jump
VehicleJump     = Feign Death

Boost             = Alternate Fire (Not Configurable)

Custom FOV

To set the custom field of view for normal driving and boosting, set the following fields under [UnrealDemolition2.UDPlayerController] in UTUnrealDemolition2.ini:

NormalFOV: default 100
BoostFOV: default 130

Note: The closer to 180 you get, the more dramatic the effect.  I do not recommend going much higher than 130, and using 180+ will break the game.
