This arcade classic from 1982 by Namco started the Digger genre proper and we haven't dug ourselves out yet. Players control the titular character, Dig Dug, as he tunnels through underground levels filled with enemies. The objective is to eliminate all the monsters by either inflating them until they burst or by crushing them with rocks. Players use Dig Dug's trusty pump to inflate enemies until they explode, and they can strategically dig through the dirt to create paths and trap enemies.
