Escape (Halo Wars level)

Overview
Escape is the fifteenth and final level of the real-time strategy game, Halo Wars. It requires the remaining UNSC Spirit of Fire survivors to open 6 interlocks to open the portal that the Spirit of Fire needs to go through to escape the Shield World before Sergeant Forge activates the FTL drive. There are forerunner symbols on each door. Serina discovers that doors marked with the same symbols must be opened after each other. Otherwise the door that is opened first will close. The forces, however only have 30 minutes to open the portal and yet have to deal with Covenant and Flood forces. With the help of the Spartans from Red Team, the Spirit of Fire successfully escapes the Shield World.

Plot
Seargent Forge and Red Team are setting up the reactor to set into the Shield Worlds internal sun to destroy the planet, when they are attacked by a large force of Elites and The Arbiter Ripa 'Moramee. Red Team, easily defeats the massive Sangheili force, and Seargent eventually kills the Arbiter by driving his combat knife through his throat and stabbing him with his own Energy Sword. The reactor, by then, is already overheated and will have to be set off manually. Jerome, the leader of Red Team, offers to set it off manually at the expense of his life, but Seargent Forge takes the responsibility, quoting that the humans will need every Spartan possible. Meanwhile, the Spirit of Fire is trapped inside the Shield World. The ground forces eventually defeat massive forces of the Covenant, Flood, and Sentinels to open up a passage that will allow the Spirit to fly out. When the reactor is set off inside the sun, the gravitational forces pull the Spirit into it, but due to some careful maneuvering by Serina, the Spirit slingshots around the sun and out of the planet. The planet, the internal sun, and countless waves of Covenant, Flood, and Sentinels are destroyed from the resulting explosion. After two weeks of no Covenant or Flood, the majority of the Spirits crew is put into cryo-pods, along with a protesting Professor Anders. When Captain Cutter walks by an open pod, revealed to be that of the late Seargent Forge he closes it, sighs, then walks off, presumably into his own pod. After the credits, on Legendary, Serinas voice can be heard telling Cutter that "something has happened."
