Really, really obscure OpenBOR demo from 2007 by a group called "Dark Concept". Most of the modes don't work, unfortunately. There's an intro with opening credits and a single actual level. Notable for being one of a few Openbor mods to use prerendered 3d models - make of it what you will. Mechanically this is one of the first Openbor games to break out of the "BOR clone" style, but it's no Rocket Viper or Crime Buster.
