High-definition gameplay footage of one of the greatest PC shooters of all time, Quake II. Almost everything about this game kicks ass: The level design, the weaponry, the music, the enemies, and even the overall "feel" of the game. What more is there to say? If you've never played Quake II before, you owe it to yourself to do so. Even today, nearly 15 years after it was released, it holds up extremely well. Quake II can be purchased on Steam for $9.99.
