The game arrived Saturday morning.
There are 23 levels, I have now completed seven of them including the first boss. I am not the quickest games player in the world.
Here's a very brief summary, imo: dated gamestyle & technology; lottsa fun; great game.
If you have even a passing interest in fps's, get this, it's a whole lot of enjoyment.
The one-liners make me laugh, I'm playing it on easy, still manage to die a fair bit but so far have muddled through. This, imo, is how games should be, choice of realistic difficulties not log in and get punched in the jaw.
As with GTA IV & Mafia II best to use keyboard/mouse for on foot and Xbox controller for vehicles.
Just buy it, it may be dated but it's great.
