Rogue Warrior, I know it's a crapy game that only took 2.5 hours to shoot through and had little if any story/plot, but killing commies as Mickey Rourke spouts gratuist communist slander that makes swearing seem like an art while portraying one of my real life heros and probably the baddest mother fucker on the planet (Richard Marcinko), makes mindless shooty blowy upy games so much more awesome.
Richard Marcinko is a real guy who created Seal Team Six (you know the guys who took down Bin Laden) and is the real life version of every action movie protagonist from the 80s. For more read his autobiography "Rogue Warrior" it will blow your mind with awesomeness.
