Order of BattleEdit
The Highway and Work CampsEdit
During Operation Hollow Storm, Delta Squad was able to locate the Locust Capital, Nexus, via the Highway from the entrance of Mount Kadar. Following a clue from the Stranded Chaps, Marcus Fenix and Dom Santiago infiltrated the Locust work camps to try to rescue Dom's missing wife. After fighting off a Locust patrol, Delta located her prison and then had to fight off a massive Locust attack on the site while JACK opened the prison. To their shock, Maria was emaciated, tortured, lobotomized and not able to even recognize her own husband. With no other choice, Dom euthanized Maria and he and Marcus decided to go into Nexus "guns blazing" rather than sneak in.
- "Baird here. There's that glyph for 'queen' and 'Imulsion' again... also see 'Nexus' on there again. These are some kind of plans that indicate an attack on the Locust... but not from above, from below. Sure as hell isn't us attacking from below, so who the hell are these plans referring to? Please tell me it's not worms. I'm so sick of worms."
- — Baird on the Locust defense map
After battling Hordes of Drones and Boomers, Delta-One was able to infiltrate the main city and battled across the outer walls of the city. After heavy firefights, Delta was able to deploy JACK's homing beacon which allowed COG troops to deploy via Grindlifts inside the Locust city, which tested the defenses of the city since the city defenses were on the lower levels.
After easily advancing into the Locust capital, Delta-One and the rest of the Gears discover the Locust are embroiled in a Civil War and it appeared that the Lambent are winning. The Lambent seem to taking hold of the city and have captured one of its outer towers. The Lambent are also in the process of capturing another one when Delta-One enter the city. Delta Squad does not meet as much resistance as they would otherwise have thanks to the Lambent forcing Locust forces to divert their guards elsewhere to stem the tide of Lambent drones.
The Palace and Locust QueenEdit
Delta reunited and entered the Locust Palace and fought their way through. There they learned from a transmission from the Queen that the Locust planned to sink Jacinto in order to kill the Lambent Locust. During their journey through the palace, Delta found a terminal that JACK hacked into and found a recording from Adam Fenix. The recording said that the best way to win the war, was to sink Jacinto and flood The Hollow to drown the Locust. Delta finally made it to the Queen's chamber where they had an encounter with the Queen and Skorge. The Queen escaped, leaving Marcus and Dom to fight Skorge while Cole and Baird chased after her. Marcus and Dom defeated Skorge, who escaped on the Hydra and Delta took two Reavers to return to Jacinto. After rescuing another Gear squad and destroying the Hydra and killing Skorge, Delta returned to Jacinto and as part of the new plan, the COG began to evacuate all Gears out of the Hollow, including Nexus.
