Machinima user M0rtanius has created another video that mashes up a classic Konami title with Half-Life 2. His original piece placed Half-Life's protagonist into the world of Castlevania, whereas this latest one features Contra. The attention to the level design is pretty neat in both, and the music is lifted straight from the NES games, but it's just not the same without the Contra arsenal and Simon's whip. Also, we're not seeing any Konami code being entered, which means a quick end could not be far behind. Check out both clips after the break.
