The TDV-1 is the only usable vehicle in the game. TDV most presumably stands for 'Terrain Deformation Vehicle' 1.
List of abilities[]
Power Boost: Rocket boosters attached to the back of the vehicle allow it to reach higher speeds allowing it to fly further off ramps. Auto Turret: Shoots at enemies automatically but can be overrided to be used manually (not very strategic since no allies accompany the player where the TDV-1 is available). Armor: Reduces the damage the user takes. Can be destroyed if compressed between an unstoppable force and an immovable object.
Terrain Deformation[]
Grind: Lowers terrain underneath vehicle during use. Ramp: Fires torpedo that creates a ramp, raising terrain. Detonation is remotely controlled unless it hits something, and causes damage.
