Install:
Place the TIMPRV.u and TIMPRV.ucl files into the system folder.
Mapmakers:
To insert it into a map, first open the map (duh). Then bring up the actor browser and click file -> open.
Select the TIMPRV.u file. Now add a HellbenderFactory. In its properties under SVehicleFactory, change
the vehicle to TIMPRV using the drop-down menu. There you have it!
Non-Mapmakers:
Once installed, the AA Hellbender should appear in Worm2k4:Motorpool and Carlauncher mutators.
Alternately, you can summon it by typing "summon timprv.timprv"
You can use this vehicle in your own maps as long as I get credited for modifying the Hellbender vehicle,
which was originally coded by Digital Extremes (I believe).
