Halo 5: Guardians

"Looks like they were designing a new stealth class vessel."

"We don't. And we don't ask. (in response to Linda asking about what is known about ONI experiments at Argent Moon)"

"Move toward the data center, Blue Team. (if the player stalls further in the first part of Mission 2 "Blue Team")"

"Accessed the databanks. Grab the data and current population map."

"Hydra launcher. / Hydra here. (if he is the first to find the weapons case with a Hydra Launcher)"

"Blue Team, report. ...Sierra 117 to Blue Team, report. ...Sierra 117. Does anyone copy?"

"I watched her die. We have a mission to focus on. We can talk about this later. Lights on."

"Frederic, get us back on course for Central Control."

"Hunters. They're keeping pace with us."

"Zealot with an energy sword!"

"Covenant ships exiting slipspace."

"Surrendering Argent Moon is not an option."

"Then forget about reaching Central Control. The plan changes to asset denial. We scuttle the Argent Moon."

"Ship's reactor core is near here."

"We overload the reactor and evac. Ship explodes, destroying any ships nearby."

"Schematics show a path to the reactor through here."

"Got it. Reactor's overloading. Move for the hangar bay-"

"We can stop that. Board the reactor."

"If it's being moved, we should go with it."

"Reach the control sheds. Get the cooling system offline."

"Frederic, find the nearest hangar bay. We're taking a Prowler."

"This station's about to be slag. Move to the Prowler."

"Sierra 117 to Infinity. Argent Moon scuttled. I've reassigned Blue Team, destination Meridian. Potential contact from Cortana-"

"Negative, Infinity. I don't like it. (said in final cutscene of Mission 2 "Blue Team")"

"Like hell she is. (said to Spartan Locke when confronted about Cortana in Mission 5 "Unconfirmed")"

"We were brought to this location for a reason. Search ahead. (said in beginning of Mission 7 "Reunion")"

"Console lit up as I approached. (if he approaches the Forerunner console first)"

"Cortana. Cortana, do you read me?"

"Wherever we are, Cortana brought us here. She's out there somewhere."

"We'll learn what's going on when we find her."

"Dead Grunt. What are Covenant doing here? Stay alert. (if the player encounters the dead Grunt in the mission)"

"Ready up Blue Team."

"More hostiles. Ready up."

"There's a Forerunner facility here."

"Break through their line."

"The path is shielded."

"Area clear. Move up. The shield lowered when the last of the Covenant dropped."

"The Didact's ship was pulled into slipspace. It could have ended up anywhere."

"More activity around the large structure."

"We keep going. We find out what's happening."

"Light bridge activated on approach."

"She called me to her. (in response to the Warden Eternal introducing himself as Cortana's defender)"

"I've come to bring her home."

"Cortana. Why does the Warden think he needs to protect you from me?"

"The Didact made it clear the Mantle of Responsibility was an imperial peace. Step out of line, and suffer."

"As Forerunner systems go. (if he enters a Phaeton)"

"How the hell are you here? (in response to Locke telling Chief that Halsey sent Fireteam Osiris to Genesis to help Blue Team)"

"I'm aware. We're at the Gateway. (in response to Locke saying that Cortana has been activating the Guardians)"

"Cortana, what is this?"

"Cortana, answer me."
