|“||Signal transmitter ready for transport of Mothership to Threshold. Successful transport to Threshold will enable planetary escape. Congratulations Foreman, mission salvaged, Mothership saved.

This bizarre, spiked building appears to grant Scrin Foremen access to the most advanced and dangerous air/spacecraft that the Scrin have to offer, namely their Planetary Assault Carriers and foreboding, glacially slow Motherships. Notably, the Mothership will materialize wherever this building is placed when it is summoned, and while this construction does indeed allow the summoning of a Mothership, it still comes at great Tiberium cost. The building itself also consumes a reasonable amount of power. With this building the Scrin Foreman can call down support power called Overlord's Wrath and summon Wormhole that provide teleportation between two points on the battlefield for a short time.
During the Scrin's escape from earth, the Mission AI give briefing to Foreman 371: "While completing Threshold Assembly, the construction of Signal Transmitter is your only chance for survival Foreman. First priority, complete Threshold assembly". The Signal Transmitter then summon the Mothership to be teleported into the Ichor Hub with the Threshold Tower.
Reaper-17 can summon three squads of Veteran Shock Troopers at a location.
This power costs $3000 and takes 1:30 to recharge.
The might of the Scrin invasion is displayed by hurling down a series of successively larger Tiberium-laced asteroids that slam into the ground with devastating impact.
This power costs $4000 and takes 7:00 to recharge.
- The Signal Transmitter bears a resemblance to an ancient sea creature called the Hallucigenia.
