Umlaut Sector

The Umlaut Sector is a solar system found in Helldivers 2.

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.

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, culling 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...

TCS Failure Incident
A month after activating the Terminid Control System, SEAF units stationed on the Barrier Planets reported a significant surge in Terminid reproduction rates. Notably, the offspring from this surge exhibited immunity to Termicide, a previously deemed impossible feat by Super Earth Scientists. The Terminids successfully infiltrated and infested the Termicide towers, converting them into massive colonies and hatcheries. The situation escalated to the extent that Meridia became overrun, rendering the planet unsalvagable.

In response, Helldivers were promptly instructed to halt the ongoing Operation, Legitimate Undertaking on the Automaton front and redirect their efforts to the Barrier Planets. Their mission: to deactivate the corrupted TCS on the remaining planets.
