Bug Breach

A Bug Breach is the Terminid's version of a reinforcement call-in. It occurs when a Terminid spots a Helldiver and subsequently sends the signal.

In order to call in a Bug Breach, one eligible Terminid changes to a specific stance, emit a unique sequence of calls and release pheromones (visible orange mist). There is an internal cooldown which prevents the call in of reinforcements until it expires. This is shorter the higher the difficulty of the mission is.
