Contra from the amazing folks at Konami was first released way back in 1987, it's a classic side scrolling, shoot em up game with what I always found was immense difficulty and boss battles that were over the top in the best possible way! Contra 4 is soon to come to my favorite handheld gaming device the Nintendo DS as well, sweet!
