This game gave me mixed feelings when I was trying to decide what to write about it for this review.
*Great graphics for it's time.
*Fun game play.
*Challenging but not that piss-you-off-toss-your-controller-across-the-room type challenge.
*It's only 1 player.
*More than half the weapons I find useless.
*No weapon upgrades.
*It has a total high score but a level high score would be better.
I picked this game up for $10 so it's well worth it but I wouldn't go spending more than say $30 on this if you can find it.
