Dig Dug is an arcade game that was first released by Namco in 1982 and was later ported to many other systems and home computers such as the Famicom, Atari 2600, and Commodore 64. The goal is to kill all the underground monsters in every level, either by inflating them to death or by dropping large rocks on them. The danger and difficulty in each level comes from avoiding being killed by enemies that can dig through the dirt without creating tunnels, enemy projectiles that can go through the dirt, and rocks that can drop on you due to your own actions.
In this run, SFan completes a full loop of all 15 unique levels in the Famicom port of this rather odd game as fast as possible.
