Halo Reach the BLOCKBUSTER prequel to Halo: Combat Evolved!
Reach takes place during the year 2552, days before the events of the 2001 video game Halo: Combat Evolved.[4] Humans, under the auspices of the United Nations Space Command (UNSC), have been waging a long war against a collective of alien races known as the Covenant. By the events of Reach, almost all of humanity's interstellar colonies have fallen. Reach is the UNSC's most fortified world after Earth, and serves as a military and intelligence hub.
