A couple of Explosive Barrels.
Barrels filled with volatile mining explosives scattered about Apollo. When shot at or knifed they, unsurprisingly, explode, greatly injuring anything near them. Explosives will instantly kill any Non-Massive, Non-Heroic enemy. This means large enemies like Agrons, and bosses like Erebos, will not be killed, but will take a healthy amount of damage.
Dangerous to Players[]
In the right circumstances players can be killed by Explosives. When a player has no Shields, the explosion from one of these barrels will kill them instantly. Because of this, players with Short Circuit need to immediately move away from any nearby explosives. Shoot any on sight from a safe distance to avoid any unwanted casualties until the Short Circuit wears off or is cured.
