While powerful, brutalisks have a very slow movement rate. Fast-moving units easily dominate brutalisks by utilizing hit and run tactics. Alternately, powerful weapons such as siege tanks, thors and battlecruisers make short work of brutalisks from afar. Every time they appear, brutalisks are optional research objectives that yield three points of zerg research in the Wings of Liberty campaign, and levels for Kerrigan in the Heart of the Swarm campaign.
In the Legacy of the Void campaign mission "Salvation" killing the brutalisk on hard awards an achievement. The best way to kill the brutalisk is with dark templars, immortals or void rays.
Brutalisks can be spawned by Abathur in the Co-op Missions mode of Legacy of the Void upon reaching level 2. They are spawned instantly when a ground unit such as roaches reaches 100 biomass. Abathur can field a maximum of three brutalisks.

The following section contains information from a previous version of StarCraft II which is no longer valid.
The brutalisk was designed initially as a unit for multiplayer in Wings of Liberty during its development. According to Phill Gonzales, the unit had gone through over ten iterations before being finally removed. Iterations included having a more snake-like body and being able to "swim" through the ground like a dolphin, and a mechanic where the brutalisk would gain an increase in attack speed and damage in proportion to how much damage it had recieved. The multiplayer brutalisk was much smaller than its campaign appearance.
