Deadlock is Valve's MOBA hero shooter, first revealed in 2024, and the Midboss is the powerful neutral monster in the centre of the map. Defeating it drops the Rejuvenator, which can revive fallen teammates, so teams contest it throughout a match. The low health cue is shared online as a standalone clip from gameplay because it sums up that turning point in seconds. Like enemy spotted callouts in other shooters, it has become shorthand among players for an objective that is close to falling.
