Their War Games session is interrupted by Captain Thomas Lasky who asks to speak with Commander Palmer. Lasky informs her that they have been requested to appear before the UNSC Security Council at HIGHCOM Facility Bravo-6. At the hearing, the council expresses misgiving about Lasky's handling of the Second Battle of Requiem. Admiral Serin Osman berates Lasky over the complete destruction of Requiem and the failed assassination of Dr. Catherine Halsey. Osman then asks Palmer if Lasky had sent Fireteam Majestic to stop her from eliminating Halsey. Wanting to protect Lasky from any ramifications, Palmer lies and tells Osman that Majestic was there as backup. Shortly after, Admiral Hood arrives onboard Infinity to speak with Lasky. He tells Lasky that the is assigned to pursue Jul 'Mdama as he needs Infinity to aid in peace talks between the Sangheili and the Jiralhanae. Two days later, Infinity arrives at Ealen IV. Lord Hood meets with the Arbiter, Thel 'Vadam, and the Brute Chieftain Lydus. Lasky, Palmer and Jackknife join the delegates inside the plasma center as Paul DeMarco of Majestic and Fireteam Bailey act as overwatch. The delegation is caught off guard when Covenant remnant forces blast into the conference chamber. The Spartan IVs defend the delegation and escort them to a nearby parts depot when their evacuation shuttle is destroyed. With communications with their orbiting fleets blocked, the delegation are left without reinforcements.

Issue 2
Official summary:

Synopsis Issue #2 opens with the delegation attempting to re-establish communication with the orbiting fleet. The Arbiter informs Hood of the planet's fortifications as a means for an escape route. Lasky orders Palmer to get the ambassadors to the redoubt. Palmer tasks Spartan Ray to escort Lasky and utilize her SIGINT background to re-establish communications. Shipmaster Vata 'Gajat and his forces arrive and is informed by Tek that the envoy has retreated into the repair depot. However, a human associate of 'Gajat tells him that they should move quickly before the capital ships respond. In orbit, while Infinity tries to re-establish contact with the delegation, the Jiralhanae contact the ship and demand to know why communication has been blocked. 'Gajat and his forces storm the depot, only to find the delegation missing. The Shipmaster orders his forces to prepare for deployment, noting that his agent would provide the whereabouts of the envoy.

The company make their way through the service conduits leading from the depot. Suddenly, a Lich appears and drops off several troops. Palmer takes her helmet filled with grenades and sends it up the Lich's gravity lift, destroying the Lich. Lasky and Ray make their way down the administrative wing of the facility taking out an Elite Warrior along the way. They find a network console and Ray discovers multiple signals being broadcast blocking out incoming transmissions. The destroyed Lich crashes down onto the service bridge while an Elite Storm unit is taken out by Spartan Scruggs. Palmer orders Fireteam Jackknife to move ahead to the redoubt while Hood searches the downed Elite. Hood discovers a UNSC data pad containing information on the Spartans and says someone is leaking information about the negotiations. Lasky and Ray secure two Banshees and make their way to the power source of the jammer but observe Covenant forces heading for the redoubt. Palmer is informed by Scruggs that the facility is secure. Unbeknownst to the rest of the group, Scruggs has instead taken out his team and the security detail.

Issue 3
Official summary: Synopsis Issue #3 opens with Lasky and Ray attacking a Covenant base and destroying the reactor, the source of the Covenant jamming signal. In the redoubt, Lydus continues to express his skepticism over whether the peace talk will succeed. Hood tells him that the Jiralhanae will need Lydus as a leader if they want to survive. Scruggs suddenly appears and holds Hood at gunpoint, stating that he will reveal his demands once his associates arrive. The situation in orbit continues to worsen as Sangheili and Jiralhanae ships begin to deploy forces against each other. Having cleared the communications interference, Lasky informs Infinity of the Covenant's attack. Upon being updated on the crisis between the Sangheili and Jiralhanae, Lasky contacts the fleets and asks them to cease their infighting and send their forces to the delegates' aid instead. However, both sides refuse to listen to him while a massive Covenant force converges on the redoubt. Meanwhile, 'Gajat and his human accomplice converse aboard the Covenant forces' flagship and it is revealed that 'Gajat is secretly working for an unknown party without Jul 'Mdama's knowledge.

In the redoubt, Scruggs continues to hold Hood hostage. He denies that he is working for the Insurrectionists and indicates that he is aware of some of ONI's secrets, including the cover-up of the New Phoenix Incident and their covert campaign against the Sangheili. Palmer then shoots Lord Hood in the leg, tackles Scruggs and, after a brief struggle, stabs the rogue Spartan in the throat with a combat knife. With the Covenant bearing on the site in force, the group find a craft they can use to evacuate. DeMarco remains behind to cover the ambassadors' escape with a Tyrant AA gun and is killed when the Covenant destroy the cannon. Thanks to his sacrifice, the delegation, Lasky and the surviving Spartans make it aboard Infinity, prompting 'Gajat's fleet to retreat. After a funeral ceremony held for the Spartans fallen in the battle, Lasky and Hood discuss the troubling prospect that someone higher-ranked than Scruggs must have leaked the location of the negotiations, indicating a severe security breach in the UNSC's hierarchy.

Production notes
Though the series primarily uses Halo 4 ' s designs for the Covenant species and their equipment, the Halo 3 and Halo: Reach incarnations of certain elements also appear in some panels. Most notably, Lydus resembles the Brutes seen in Halo: Reach, yet his bodyguards are clearly drawn in their Halo 3 likeness. Pre-Halo: Reach and post-Halo: Reach Banshees are shown side-by-side in Issue 2, and a Halo 3/Reach-style Grunt makes a cameo in the same issue. Curiously, despite his recognizable classic appearance, Escalation depicts the Arbiter much like the Sangheili in Halo 4 with regard to his skin tone and mouth structure.

Mistakes

 * In some panels in Issue 1, Kig-Yar are seen with four fingers instead of three.
 * In Issue 1, the visor color of the Spartan with War Master armor is orange, yet in Issue 2 it is blue.
