Completed the single player in one sitting, took 7 - 8 hours and thats with looking around at times. Going to go through it again on the hardcore settings and try and do a few of the side missions in the levels etc. Multiplayer is decent, needs a bit of patching on the PC side of things, but very little in the way of bugs and issue's I've come across. Once the mouse sensitivity stopped responding but a quick restart of the game sorted that out.
Overall, not a bad way to spend a Sunday afternoon, as you would expect the dick jokes get old fast, story is lacking to say the least but a great all out shooter with the added bonus of trying to get as imaginative as possible on your kills
If anyone else got the game on the PC, add me to the steam friends list and I am more than happy to co through the MP with hexus members Easiest way to find me is probably on the Hexus steam group
