Since the success of the "All-Out-War" Skulltag mod, it has become apparent that pilotable vehicles are completely possible. Originally, RoboDoom was designed for the player to play AS a Veritech/Valkyrie. Now, we can have player classes that include all races and sizes. As you can see, I've gotten the Quake2 models made by Dan Bickel and others into the game. I think they look great.
