Galileo Base

Galileo Base was an important science research facility on the surface of Requiem during the Second Battle of Requiem.

Second Battle of Requiem
When the UNSC first arrived on Requiem, they established several science bases to study the Forerunner planet. Galileo was one of these bases.

Some point during the battle, the base came under attack by the Covenant Remnant. They enlisted the help of Fireteam Crimson to help restore AA Guns within the bases perimeter to help shoot down phantoms that keep deploying troops. The base was cleared.

Later in the battle, the Covenant attacked the facility again but this time it was because it now held "The Diadect's Gift". Fireteam Crimson helped restore and defend the base while Fireteam Majestic moved "The Diadect's Gift" to safety on board the Infinity.

It was later most likely destroyed when Requiem was pulled into its star. Currently, its existance lives on through the Infinity's war games simulation as War Games Map_Set/: 615-3 or 'Complex'
