Polaria systems was a secretive research facility situated deep underground. It was a conglomerate of brilliant scientists and visionary thinkers who foresaw the nuclear war and wished to preserve the knowledge of the old world while pushing the boundaries of what was previously thought as impossible. Establishing their facility deep underground meant they could maintain a high level of secrecy and protect their work from prying eyes.
As the sole survivor, you stumble upon the Polaria Systems near the west edge of The Commonwealth, and quickly uncover that the facility has has recently been overtaken by the Gunners.
Polaria Systems is my newest dungeon mod for Fallout 4 , being over a year in the works, it features a enormous dungeon providing several hours of gameplay aswell as a new weapon; the Gravity Grenade!
