Megalith
Megalith was an Erusean superweapon built on the Twinkle Islands. It was designed to weaponize asteroid fragments in orbit around Earth; the facility launched missiles that struck fragments in such a way that they would change their course and crash onto the planet.
Megalith was constructed in secret during the Continental War and immediately activated as a retaliation weapon following Erusea’s defeat. The ISAF Air Force’s Mobius Squadron, led by Mobius 1 and supported by Bravo Team, subsequently destroyed the facility.
