Stealthbender

The Stealthbender is an Axon vehicle enhanced with Necris technology, that was supposed to be available in the Unreal Tournament 3 campaign mode after completing a certain mission.

Right now, my favorite vehicle is the Stealthbender, which is a Hellbender hybrid that's been mutated by Necris technology. I really like that thing, because it deploys things like teleporters and all these different things on the map. Just in general, having a stealth-based vehicle is fun.

The vehicle's entire content was removed from the game before shipping and the only leftovers are some non-functional classes. The StealthBender has been replaced in functionality (as described by Jeff Morris above) by the Necris Nightshade.
