Midway between common Spectres and Titans, Reaper Brawlers will relentlessly advance on Hardpoints and the enemy base.
— In-game description
The Reaper Bruiser is a variant of the Reaper that can be deployed as a Burn Card in Titanfall: Assault. The Brawler, like Spectres and other infantry units, can deploy anywhere on the map via Reaperfall. It captures Hardpoints and will otherwise push objectives by itself. It is designed to be the last step before reaching a full-on Titan in strength.
The Bruiser fights using its fists, and cannot attack drones. It is considered a Titan for targeting purposes (IE titan-seeking units like the Boomer, the Gunner and the Sniper Ion will stop movement to attack it). Although it resembles a Titan, it does not enter Doomed State, instead simply being destroyed when its health is depleted.
