I played a couple of hours of it a couple of years ago. It wasn't painful but wasn't anything special. If you don't have any other shooters around, you could probably get $3 of fun out of it.
I remember Brute Force being rather fun. It was also a pretty long game for a shooter, if I remember right, I put 10+ hours into it, and never beat the game (still on my list of games to go back and try to finish up).
Hard to say if it's held up well, but for $3, if you have any interest, I'd pick it up
