Infested terran (StarCraft)

Infested Terrans have more hit points than Terran Marines and much greater speed. They don't normally have a regular attack, but can explode to do 500 points of explosive damage. This will destroy many structures and nearly any ground unit.

Infested Terrans are produced from the Infested Command Center. To acquire one, the Zerg player must infest a damaged Terran Command Center with a Queen. In some games (those without a Terran opponent) the structure is not available, so Infested Terrans cannot be created.

Infested Terrans are created with a queue rather than through larvae; they are the only Zerg units created this way in StarCraft I.

Strategies
Despite their hit point and speed increase, Infested Terrans aren't particularly effective, as they are easily killed before they can get to their target. Covering them with Dark Swarm is a way around this weakness.

One strategy that can be effective is combining the abilities of Overlords with those of Infested Terrans. Fully-loaded Overlords can literally go on bombing runs over an enemy base, dropping the Infested Terrans as they fly. It is a risky strategy as the Overlord can be caught and destroyed, but the eight Infested Terrans that an Overlord can carry have the capacity to cause severe damage and chaos.
