Volatile infested

Volatile infested are a breed of zerg infested terran found after the zerg infested the Umojan Protectorate research team on Jarban Minor.

History
Volatile infested were made from the infested research team on Jarban Minor after the zerg overran them. They appear to be similar to normal infested colonists, but with a large explosive pustule on their chest, which explodes when it gets in range of a target.

When Agent Nova Terra arrived on Jarban Minor in search of terrazine, she was forced to fight off waves of these creatures, which swarmed the extraction devices as she tried to harvest from them.

Gameplay
Volatile infested appear in the Nova Covert Ops mission Night Terrors. They function as slower moving banelings, but do higher damage. When harvesting from an extractor, waves of them will often appear from nearby caves, particularly those from the southeastern most extractor. Area-of-effect such as siege tanks pr Nova's grenades can do well against clustered volatile infested. In addition, HERCs are immune to their acidic explosions.

Trivia
Volatile infested appear to be a reference to the infested terrans from the original StarCraft, as they both function as explosive suicide units.
