Lost soul (Doom 2016)

The lost soul returns in the Doom in a form almost identical to its classic version, a flaming skull with demonic horns which rushes toward the player to attack. These lost souls however replace the bite used by their counterparts with a -style attack wherein they will explode upon contact with their target, dealing significant damage.

Tactical Analysis
Health: 75

The Chainsaw cannot be used to kill Lost souls.

Due to their small hitbox, any precise weapon will work well by sniping them from a distance (e.g. HAR with Precision Scope).

Lore
Lost souls are described in the Corrax Tablets as being the weakest form of demon. They lack a physical form, and are despised by the other denizens of Hell. Lost souls home in on a potential host before exploding in a burst of Hell energy. If the host is sufficiently weak-willed, the demon will possess the host and the host's soul will then become a lost soul itself.
