obj_monster is an olive-green rectangle that appears to be a monster. Its prototype design was never finished as it was made really early in development but scrapped (almost) instantly.
Behaviour
obj_monster slides around, hurting the player upon contact. It can also jump through pushable barrels (not usable barrels) and start walking faster when the player is behind it.
Trivia
This is one of the very few enemies to just appear in one build and nowhere else.
