HIDEOUS MASS is almost entirely made up of featureless meat covered in armor that protects it from attacks. It is 70ft tall. It cannot move, instead shoot homing bombs at you. It can slam into the ground, creating a shockwave, and shoot a harpoon at you to prevent you from moving. Shoot the creature's tail to release yourself. HIDEOUS MASS is made up of massive Hell Mass clumps to get its shape.
