No Mutants Allowed is hosting the Black Isle Studio's Van Buren tech demo (Van Buren is BIS' cancelled Fallout 3 project). Keep in mind this is a pre-alpha tech demo from 2003: the combat is pretty much unimplemented, the graphics are really basic and it crashes frequently. The tech demo is locally mirrored (thanks: Blues).
