Absolutely Gruesome!
Shooting a guy's head off with one shot and watching it roll across the floor is so grin inducing, it's just so satisfying when you kill the bad guy. Must have been why they rated this game mature not just from the bad language but also because of all the blood and guts! I mean it's absolutely gruseome...
When you kill a bad guy if you use a machine gun thier limbs get shot off and blood goes everywhere, great fun! I shot one with a machine gun so many times that he actually liquefied into a pool of blood on the floor and splattered all over the wall... Excellent!
All in all this game is great and it also has net play so you can shoot your mates heads off too! I can see me playing this game for while, I've only got to about level 5 and already there has been a good selection of weapons from the Sniper Rifle to the Grenade Launcher and tons of bad guys to kill.
Well worth a look, if you see it in the shops -buy it! and the as it's now an old game I only paid £6 which is about $10 Dollars so, good value for the money...
