High-definition gameplay footage of id Software's Quake, one of the first true 3D first-person shooters ever made. Although its development was hampered at times and it would mark John Romero's last outing at id, Quake would go on to be critically acclaimed. Some of its fans even prefer it over other grandfathers of the genre like Doom and Wolfenstein 3D! If you would like to give it a shot yourself, Quake is now available on Steam for just $9.99.
