Infested diamondbacks also have the ability to fire fungal snares that root air units to the ground.
Infested diamondbacks appear as a unit in Co-op Missions for Alexei Stukov. They are buildable from the infested factory, and are able to root air units. Like their terran counterparts, infested diamondbacks can fire on the move. Stukov's infested diamondbacks can be upgraded to leave behind a trail of acid, damaging enemies caught in it.
