The Guns of Infinity
From Halopedia, the Halo wiki
Multiple waves of Covenant invade the Engine Room. Spartan Jared Miller orders Crimson to seal five emergency bulkhead doors. Crimson fights off the invading Covenant and closes all five bulkheads, securing the Engine Room for good. Roland then informs them that UNSC Infinity's aft weapons have gone offline due to the cooling systems being shut down. Miller orders Crimson to aft weapons control.
Crimson fights their way to Aft Weapons Control where they find the Covenant have set up several hardware override devices which are interfering with the weapons' cooling systems. The Spartans destroy the override devices, but the guns still won't fire. While Roland tries to determine the problem, Crimson is forced to fight Prometheans and Hunters. After Aft Weapons Control is secured, Roland shows Crimson how they can reactivate the ship's guns. Crimson bring the guns back online. A nearby CRS-class light cruiser is destroyed by the reactivated weapons systems. Miller informs Crimson that they can now start cleaning out the remaining Covenant onboard.
