Sniper Alley

Sniper Alley is the UNSC codename for a location on the Forerunner shield world Requiem.

History
The Sniper Alley location is an area on Requiem that leads to the power core for the planet's Particle cannon network and the AI personality of theLibrarian. John-117 entered the area to neutralize the particle cannon network to allow him to reach and destroy the Gravity well holding the UNSC Infinity on the planet. After clearing Unggoy and Kig-Yar from the area, John-117 faced Promethean forces. He managed to defeat all of them and progress within the structure and disable the network.

Six months later Covenant remnant forces had put up an energy source and were drawing energy from the Forerunner mechanisms within the planet. The UNSC Infinitysent in Fireteam Crimson to locate the power source and eliminate the Covenant in the area. Crimson was successful and an air strike was conducted, destroying the generator. Crimson then was extracted from the area. Later en route to the Refuge, Crimson's Pelican was shot down by Covenent-run Forerunner anti-air turrets. Crimson managed to survive, clear Covenant from the location yet again, and disable the turrets. Crimson then contrinued to the Refuge. Despite their two defeats, the Covenant did not give up on the location and re-established a presence, secretly communicating by using a generator in Sniper Alley. Once again, Fireteam Crimson had to eliminate ther Covenant at the location and destroy their target prior to extraction.
