Relay

A band of Noise Marines have seized control of an Imperial communications relay and are using it to pump out their corrupting babble across the air waves. The command disruption being caused is bad enough but the weak-willed are being reduced to little more than zombies by the attack. The communications relay must be recaptured if possible, failing that it must be destroyed.
