Trivia
The achievement is named after speedrunner Scurty. The "bump" is most likely referring to the "Flood Bump" technique which makes use of a reviving combat form to bump through the dislodged wall at the very beginning of the level. It may also refer to the older "shield bump" technique which uses the Covenant portable shield farther down to bump through the walls and get into the bridge of the ship.
