The Digger is the first alien and a basic enemy introduced into the game. These enemies have average speed, low health, and below average attack. Alone, they do not pose much of a threat to players with higher-HP armors, although Diggers frequently come in groups and therefore become more of a threat. Compared to the Mambull and other aliens, Diggers are far more common and somewhat easier to deal with. Diggers also have mutations; their mutations have higher HP, speed, and damage. Digger mutations appear uncommonly. Both types of Diggers will attack by slashing at the player with their tusks.
