“Look out, everybody, things are about to get awesome!”
Mortar is an optional mini-boss encountered during the story mission Toil and Trouble.
Mortar's most prized possession is a custom buzzard, which he calls the Boombringer. He is never seen flying it, but Boombringer is destroyed in order to anger Mortar and trick him into bringing the elevator down.
Killing Mortar is optional but will fulfill an optional objective.
