Plague
A powerful ability that causes all units affected by the ability to take damage. This ability is effective against the Protoss and Terrans because if used against the Protoss they take damage even if they have Shields. If used against Terran structures the Terran structures will take damage until the health meter is at the Red Zone and they will burn up until they are destroyed. This ability does not kill units but it is effective against Battlecruiser fleets if they are group together.

Infest Command Center
This ability only works if an enemy Terran Command Center is weaken enough so please damage the Command Center to half of its health points and then send a Queen to infest it. After infestation the Command Center can be ordered to lift off to move to a safer place or it can build the most powerful attacker in the game, the Infested Terran.
