Very surreal. And fun.
The graphics for its time were pretty IMPRESSIVE. True 3D, unlike Duke Nukem or whatever which used sprites. The levels are pretty insane, some are wacky colourful ones, some are dark apocalyptic looking dystopia types. ALL ARE FUN. The characters are hilarious. You have a sidekick dog with 4 arms who flies a crazy aircraft which drops fang-like bombs onto any target you designate. The enemies are also strange. Pretty much all of them seem to be robotic, there's even a crazy sort of cyborg-hound thing. Also suicide bomber grunts that scream while running at you carrying a huge explosive shell.
