This was a third person shooter where you played as a little yellow droid named "Glitch". I guess if I could compare this game to anything, it would probably be Ratchet and Clank. You have a large arsenal of weapons at your disposal, from the standard machine gun, missile launcher, ect. to some of the more creative weapons like the Ripper and the Control Tether. The former of which cuts off or damages enemy limbs while the latter allows you to take control of your enemies provided you can get behind them.
What's interesting about the enemies of these games is that they react depending on what parts of their body you damage. For example, say you're facing a Mil Grunt, if you hit his torso enough, it bends over and he runs around in circles firing wildly as he can't see where's he's going. If you shoot his arm enough times, it blows up or goes limp, so he can't fire or throw grenades, (depending on which arm you shoot at) The enemies in this game also have a lot of personality to them as well. They react to them getting shot by friendly fire, they run around and scream whenever they are heavily damaged, ect.
The game had some variety in it's missions as well. In addition to the standard point A to point B missions, you also had vehicle missions, protecting a town, a few missions that have you play as different characters, and a mission where you infiltrate a spy factory where you pass yourself off as a spy so you can acquire a special chip.
The story itself is nothing revolutionary, but it's decent for what it is. The characters are fun and diverse. Particularly the foul mouthed droid mechanic Krunk.
This game unfortunately ended on somewhat of a cliffhanger, and there were plans for sequels that would reveal more of the world of this game and Glitch's origins. However, the game didn't sell very well and due to some legal stuff with Activision, of which I don't know all the details, the franchise may never see the light of day again.
It's a damn shame really. This was a fun as hell game. It deserved a lot better.
If you want to play it for yourself, it's available on the PSN and (if it's still around) XBOX Live on the 360.
If you can, I'd recommend the XBOX or GameCube Version as the PS2 suffers from lower frame rate and the graphics and sound quality take a bit of a dip.
