Eat Lead: The Return of Matt Hazard only took me about 12 hours to complete, which is pretty short, and although it starts out fast, it slows down on the entertainment value as you make your way through the levels.
After you get beyond the jokes and cheap thrills, Eat Lead is really just a sub-par, straight-forward shooter with levels that turn into shooting galleries. Many times, the enemies come straight for you or run across the room before looking for cover, making them very easy to pick off.
