Kill Team is a fast-paced tabletop skirmish game by Games Workshop, where players command small, elite squads of soldiers from various factions in intense, tactical battles. Set in the Warhammer 40,000 universe, each player builds and customizes their team with unique operatives, equipment, and abilities. Kill Team: Brutal and Cunning includes two new kill teams. The Wrecka Krew features a Boss Nob, five Orks, and two Bomb Squigs, while the Ratling squad consists of 10 Ratling operatives, a battlemutt, and their leader, the Ratling Fixer. The set also comes with the Killzone Upgrade: Compound Siege, which includes two bunkers, six fire steps, and six stockades for use with Killzone: Volkus.

Additionally, the 72-page softback Brutal and Cunning dossier is filled with lore about the mission and the kill teams, as well as rules for the Wrecka Krew and Ratlings. It also includes the Volkus Compound Mission Pack, offering PvP and PvE scenarios. The set is complete with datacards, tokens for both teams, and an Ork transfer sheet containing 438 transfers.
