The Infestor is a radar-stealthed support bot that doubles as a combat engineer and short-range brawler. Equipped with a light heatray for close-quarters defense and the ability to reclaim and repair, it can also build other Infestors, making for a self-sufficient, all-terrain, stealthy strike force.

Infestors take only one-fifth the 'damage' from EMP weapons, making them difficult to stun.

Infestors have mild damage for their class, and can easily be outgunned. However, they have extremely low build time for T2 units, which makes repairing heal them faster.
