Wall Creep

Wall Creeps will try to line up with Isaac, and shoot three blood shots quickly in a horizontal line.

They have a long blood-shot range, but Isaac can attack them safely by shooting diagonally.

Blind Creep
Blind Creeps will crawl along walls randomly and shoot 3 spreading blood shots, like. They are slower than Wall Creeps, fire less frequently and do not directly target Isaac, but their shots are less predictable.

Rage Creep

Soy Creep
Soy Creeps will try to line up with Isaac and fire a continuous stream of shots that are seemingly affected by. Their range is quite impressive, rendering them able to hit Isaac when he cannot see them. In dark areas, the rooms are illuminated by their eyes.

Tainted Soy Creep
