Don't bother
I'm not really into twitch shooters, or arcade-lightgun-style games, so even if this was well-made I don't think I'd enjoy it all that much.
That doesn't matter, since the game is terrible. AI is awful, level design is awful, weapon feel is awful, controls are... pretty bad, graphics are awful. There's no checkpointing, but that wasn't an issue because before I got through the first level I just used the cheats that are listed directly on the control help screen. I guess the developers left them there to be kind to players like me.
It's not even so-bad-it's-good, and you don't get a reward for playing through it, or extra items or levels or anything like that.
My experience wasn't all bad though. Here's a short list of positive things about this game:
- I got it in a bundle for 'free', since I paid less than retail for other games in it that I wanted
- None of the many bugs I encountered actually crashed the game
- The installer takes up less than 57 MB of space
