Little Crawler

Any weapon: knife, handgun or shotgun; a grenade for groups

A small seven-legged spawn with a single red eye. Its only attack is a leap: block it or sidestep. It explodes afterwards, hit or miss. If you aim at it, it hops back. Neuro-stun Grenades kill them.

Endless in the Storage Area Sewage after you restore the power, 1 in section N3, and endless around the Mama Mold. Professional adds more in the Mine Cart Yard and 3 in the Research Facility Monitoring Room. Professional: in Marquez's room they run into the traps and set off an explosion that kills both Chris and Marquez.
