Completing this level on [[Normal]] or above unlocks the map ''[[Last Exit]]'' on [[Firefight (Halo 3: ODST)|Firefight]] mode.

As the [[Battle of Mombasa]] enters its final stages, the [[Rookie]], [[Edward Buck|Buck]], [[Veronica Dare|Dare]], and [[Quick to Adjust|Vergil]] fight their way to the [[New Mombasa|city]]'s Coastal Highway, where Dare and Vergil board an [[Olifant]]. Buck and the Rookie escort them along the [[Covenant]]-infested highway with various [[M12 Warthog|Warthogs]] and a [[M808B Main Battle Tank|Scorpion]], hoping to reach the shipyards for extraction. However, a [[Deutoros-pattern Scarab|Scarab]] manages to cripple the Olifant, forcing the group to divert off the highway to a nearby building. There they fight off waves of Covenant until they are finally saved by the [[Ru'swum-pattern Phantom|Phantom]] that they captured earlier. Reunited at last, the [[Alpha-Nine|squad]] leaves the war-torn city just as it is glassed by [[CAS-class assault carrier|assault carriers]] and [[Ket-pattern battlecruiser|battlecruisers]].

*'''Buck''': "Sit tight. We'll need the alien to power on the switch."

''View of the Highway at dawn opens. Cut to Dare, The Rookie, Buck, and Vergil moving forward. Covenant {{Pattern|Ket|battlecruiser}}s fly above. Dare points to one.''

''The Rookie tries to motion to the two that the Huragok is gone, but to no avail.''

''A cruiser drops out of slipspace attracting the attention of the squad.''

*'''Buck''': "[[Kikowani Station|I stole a]] [[Ru'swum-pattern Phantom|Phantom]]. Yes. Thank you. I hid it in the shipyards down the highway. ''(looks towards a nearby Warthog)'' But I only have room for two, so...that thing's gonna have to sit on your lap."

*'''Buck''': "What are you, crazy? Stop moving around, and drive this Hog!"

''The second door opens, revealing a lookout tower with a Grunt wielding a [[Pez'tk-pattern fuel rod gun|Fuel Rod Gun]]. A Covenant battlecruiser flies over them.''

*'''Dare (COM)''': "They're all heading to the slipspace crater, the Covenant dig site north of the city."

''Two Wraiths and some Covenant infantry fill up the highway, but the group speed past them to the door. The small group of Jackals and a [[Jiralhanae|Brute]] are defeated. Next to the door is another Warthog. Phantoms drop off reinforcements and fly away. Another Covenant cruiser flies over them. A group of [[Karo'etba-pattern Ghost|Ghosts]] crowd around a crashed Phantom. The group defeats the Ghosts and heads to the next door.''

''The door opens to reveal the next section of the highway. More Phantoms come. A huge group of Ghosts and Banshees come, but Buck easily takes them out. The door opens at the end. The next section has a [[Deutoros-pattern Scarab|Scarab]] in the distance, along with some [[Type-26 Banshee|Banshees]]. The Engineer emits a high-pitched wail in the presence of the Scarab.''

''A Covenant [[Zurdo-pattern Wraith|Wraith]] appears.''

''The two commandeer the Scorpion, and the door opens. They move down the Highway, crushing any Covenant in the way. They head through another set of doors. A {{Class|CAS|assault carrier}} appears from the clouds in the distance.''

*'''Private First Class [[Michael Crespo|Michael "Mickey" Crespo]] (COM)''': "Sky's kind of crowded, Gunny."

*'''Corporal [[Taylor H. Miles|Taylor "Dutch" Miles]] (COM)''': "Romeo, take the one on the left."

''The ground suddenly shakes as another Covenant assault carrier exits slipspace dangerously close to the surface. It begins charging its energy projector. The Huragok sees the assault carrier, seems to panic, and refuses to move. Dare attempts to drag the Huragok to the Phantom.''

'''[[Quito Terminus|ONI orbital facility]]'''

*'''[[Sergeant Major]] [[Avery Junior Johnson]]''': "Don't worry...''(tapping a control panel)''...I [[Halo: First Strike|know]] [[Metropolis|what the aliens like]]."

'''''Easter Egg''': At this point, if the right thumbstick is held left, one can see Buck with a [[Cavemen|Caveman]] which is sitting on a grating. Buck nervously picks something off of the monkey (possibly a bug), and proceeds to put it in his mouth.''{{Ref/Site|URL=http://halocinema.bungie.org/halo3odst/hd/epilogue_easter_egg.wmv|Site=Halo.Bungie.Org|Page=Halo 3: ODST Cutscene Library - Epilogue Easter Egg}}

'''{''Legendary-only Scene''}'''

*The [[Vidmaster Challenge: Deja Vu]] can be unlocked by beating this level with four players on [[Legendary]] [[Xbox LIVE]] [[Campaign#Cooperative|Co-op]] with [[Halo 3 skulls#Iron|Iron Skull]] activated and without using Warthogs or Scorpions.

*The Tilt skull can make the highway section nearly impossible on higher difficulties. As the player only has access to [[Warthog]]s and the Tilt skull greatly reduces damage from bullets against shields, it is significantly harder to protect the Olifant before it is overwhelmed.  

*The player can also hijack the [[Ogab'd-pattern anti-aircraft Wraith|AA Wraith]] in this level using the same [[Drive an AA Wraith|glitch]] that allowed the player to hijack them in ''[[Halo 3]]''. Buck will say that he will man the AA Wraith's turret but actually will continue on foot. It is unknown if getting the AA Wraith will invalidate the Deja Vu achievement, which explicitly bans only the use of Warthogs and Scorpions.
