Two Giants

Two Giants is the codename for a canyon on the Forerunner shield world Requiem, named for a pair of pulse-emitting towers on either side of the canyon. It saw occupation by both the Covenant and the United Nations Space Command during the Second Battle of Requiem.

UNSC investigation and Covenant counterattack
In February 2558, the area known as Two Giants was under Covenant control. Mountain Squad, a joint Spartan/Marine unit, was deployed to the area to investigate a mysterious signal received at Galileo Base. Their D79-TC Pelican crashed behind enemy lines and the survivors came under fire. In response, Commander Sarah Palmer deployed Spartan Fireteam Crimson to the area, where they engaged and linked up with Mountain Squad's surviving Spartans. Though the Spartans of Mountain Squad were killed, Crimson investigated the southern tower, which Dr. Catherine Halsey surmised to be the origin of the signal; at this time, the tower emitted a pulse into the sky, which alerted nearby Covenant forces.

Responding to the pulse emitted by the tower, a arrived near Two Giants and deployed waves of Type-44 Phantoms to Crimson's position. Spartan Robert Dalton requested several Mantis assault mechs for the team, which they used to thwart the Covenant's reprisal. Eventually, 's Sub-vessel 3 destroyed the cruiser and Crimson was redeployed.

Later conflict
The UNSC soon established a base at the inland tower. After Covenant Supreme Commander Jul 'Mdama was reported to be present at the other tower, Fireteam Crimson was sent back to Two Giants. On their arrival, however, the Spartans encountered only Promethean constructs, which were soon reinforced by the Shipmaster's forces. 'Mdama had used the tower to teleport himself to the Fortress, a structure elsewhere on Requiem. After clearing the area, Fireteam Crimson entered a portal inside the tower, translocating them to the Fortress in pursuit of their target.

Production notes
Two Giants is the location of the Halo 4 multiplayer map Ragnarok; in-universe, the map is based on the conflict depicted in Spartan Ops, as evidenced by the presence of Mountain Squad's crashed Pelican. In the real world, the map is a remake of the Halo 3 map Valhalla, which in turn is a spiritual successor to Halo: Combat Evolved ' s Blood Gulch and Halo 2 ' s Coagulation. Valhalla and Ragnarok are both named for elements of Norse mythology.

The map is an almost exact recreation of Valhalla, which is canonically set in a nearly identical canyon on Installation 00. It is thus interesting to note that Pelican Victor 398 and Mountain Squad's Pelican crashed in the same manner in the same approximate locations in their respective canyons. From a production standpoint, of course, this is due to Ragnarok being a remake of Valhalla.
