If you wanna fart around with bots for a bit, it's kind of fun. The concept is that each attack is not just a weapon, you actually become a different monster. Oh dear... It's a cool idea, changing your whole persona instead of just switching weapons.... but in practice it is problematic. If you are chasing around a character and they change into another one, well, it is an awkward mechanic when you have several characters running around who all keep changing. Which one was I shooting at? I guess this could be seen as interesting or challenging, but I found it simply confusing and frustrating, which is a bit of a shame.
The base movement and feel is very similar to Quake, which is awesome. The characters look really cool. I think this would be better as a champion type shooter, where every character has a special move or ability but access to the same arsenal. And they either don't switch, or thats a power up. Most of the weapons / personas are fine but a couple are unintuitive or meh. Basically there are only eight pretty good maps. You have to manually add bots in practice matches, instead of there being a proper bot selection screen. There was no ui for changing bot skill. The animations and effects are mediocre. The sound effects for the monsters are pretty campy, which does add some comedy value. Everything looks ok, but it probably should look better in UE3.
If you make a multiplayer only game, but ain't no players, then don't bother to make the practice matches fun and featurepacked, you have problems. I'm rating this thumbs up because it is so cheap and clearly some love went into this, but the game needed more testing and help.
