TCS Towers

With the Terminid Outbreak at the start of the galactic war threatening to spread out of control, Super Earth scientists developed the Terminid control system: a planet-wide bug extermination network. The TCS would be constructed on an unbroken line of barrier planets in the Umlaut Sector, with the plan being to quarantine the bugs behind them.

Activation of the Terminid Control System
After the bugs were pushed back to the barrier planets, where after weeks of work SEAF engineers had finished a building a network of massive, Termicide-dispensing towers upon each Barrier Planet: the key to the Terminid Control System. Once activated, the TCS would exterminate every Terminid on that planet, and inoculate it against all future infestations. However, surges in Terminid activity also forced the SEAF Engineers to evacuate, with the Helldivers being sent into activate the Terminid Control System at any cost.

The Terminid Control System would later be successfully and fully activated several days later thanks to the efforts of the Helldivers. The Termicide would work as intended, killing millions of Terminids on the Barrier Planets. Super Earth's citizens could finally rest easy, knowing their children were forever safe from being eaten alive by fascist insects.

However unconfirmed reports, antidemocratic rumors and unpatriotic conspiracy theories say that the Termicide, an Anti-Terminid Neurotoxin dispersed by the TCS Towers, is causing the Terminids to mutate and evolve faster. These rumors and conspiracy theories are all slanderous and defamatory, and most of all untrue, and any Helldivers or Citizens that is caught in the act of spouting such rumors must be reported to your nearest Democracy Officer.

De-Activation of the Terminid Control System
The terminid control system was discovered to cause mutations in the bugs that allowed them to reproduce rapidly. Gaining an immunity to its deadly effects, Terminids attacked the planets that hosted the TCS, and we are now tasked with taking down the previously established TCS

Trivia

 * The terminid control towers in look and function are giant bug sprayers, pumping neurotoxin into a planet's atmosphere.
