Weapon Chest Mimic Stats First area: Scrapyard Health: 30 Damage per shot: 0 Melee damage: 5-10 Rads dropped: 10

The Weapon Chest Mimic is an enemy that mimics a Large Weapon Chest. After beating the Nuclear Throne boss with Big Dog, Large Weapon Chests will randomly turn into Weapon Chest Mimics for every character. There's a 1/5 chance after the Sewers area that a Large Weapon Chest becomes a Weapon Chest Mimic. They explode on contact dealing 5-10 damage. Once the Mimic is killed, it will drop six weapons ignoring current game difficulty and 10 Rads.

There are a few ways to find out whether a Large Weapon Chest is a Weapon Chest Mimic or not:

It won't have the "shine" effect that regular chests have,

It will play an animation showing its teeth every once in a while,

In the end the easiest way to know whether your chest is real or not in the heat of battle is to just shoot it.
