I picked this game up at launch.
The game itself handles decently, but there was so much room for improvement in gameplay that I've been turned off from picking up this title and playing it through again. For one, it seems as if 90% of the bullets you fire are blanks because they don't do dick all to any of your enemies. For two, the cover-to-cover system is a neat idea, but it isn't very well executed. I quit using it after the first couple of levels because I would point at cover and Matt would sort of head in that general direction and hide right in front of the enemies who were actively firing at me. For three, THE GAME LAGS. I shit you not. I don't know if this is done on purpose (IE making fun of lagging games) or if it was just accidental, but there is no reason why a game, whose graphics look somewhat dated, should lag! ESPECIALLY when Matt makes the most amusing of comments about the frame rate if you stand still long enough.
The humor in it was low-brow, but I'm not going to lie and say that I didn't enjoy it. I liked that the game was poking fun at video gaming in general (for some reason I found it hilarious to pick off Space Marines with my trusty Water Pistol, which seemed to be the most accurate weapon in the game). Matt Hazard's generic 'manly bad-ass voice' was a bit grating at times, but NPH stepped up to the plate and did an awesome job, which made me smile. The ridiculousness of the whole game made it worthwhile to play, but there are so many other games out there now that pull off over-the-shoulder-shooter style gameplay without lagging. Honestly, though, it is worth a rental, if only to laugh at it.
