Tickers (called so because they emit a 'ticking' sound, and explode like a time-bomb) are small creatures that the Locust use as mines, mainly against COG vehicles. However, they are also devastating to COG infantry, and are used in this way particularly by the Kantus, who summon them 2 at a time and use them as a last defense when under direct threat by COG units. They are quick moving and relatively difficult to detect despite the sounds they emit, making them dangerous and unpredictable adversaries, especially in large groups. Due to the gas released by tickers when about to explode, and the tanks mounted on their backs, it would seem that Imulsion is used to cause the explosions.
