It's actually the first game I got on GC. It's totally freaking amazingly awesome, BUT ... it's so intense and difficult that it'll burn you out after like fifteen minutes of play.
And you may ask yourself, 'Where does that highway go to?'

And here's a screenshot of the as-yet unreleased final version of some late-level bosses:

I don't have it, but I've played it at a friend's house before. It's pretty fun, and I hear you can beat the entire game without firing a single shot. You'll need a bit of practice if you want to advance to later levels though - is it fun? Yes. However, IMO, it's not worth the money if I can just borrow it from a friend. I'm gonna be saving up for HL2 and upgrades to go along with it, then maybe Starcraft: Ghost.
