Crawler Molded (Not a Hero)

The head; a Grenade kills it instantly

Fast and on all fours: it leaps and claws. Shotgun up close (Thor's Hammer - AW Model-02) or sneak up on it. Plan for Shield Machine wave 2, which brings 4 at once.

900 HP (400 in the Professional infected tunnels; datamined). Normal: 12 (16 on Professional). Work Sector A: 1 after most of the Molded, 1 in the NE offshoot and 2 after the arm bomb; Repair Yard: 3 when you take the Clown Key; Mine Cart Yard Corridor: 1 after the Clown Key; Shield Machine: 4 in wave 2.
