For the location in New Mombasa, see Tayari Plaza. For the achievement, see Tayari Plaza (achievement).
Tayari Plaza is a Halo 3: ODST campaign level. It is the first level to be played from Buck's point of view, and also the first flashback level in the game. Completing this level on Normal or above unlocks the Tayari Plaza achievement as well as the Edward Buck character for Firefight mode.
The Firefight level Crater is based on the end of this level.
Directly after the drop, with the aftereffects of the in-atmosphere Slipspace rupture washing over the city, Buck survives a rough landing and moves toward Dare's crash site in Tayari Plaza through hordes of Covenant. Scattered Marines provide limited assistance. When he arrives, Dare is nowhere to be found. Instead, Buck is confronted by a Covenant Engineer holding the charred remains of her helmet. Romeo appears and kills the creature, and the resulting explosion propels the helmet into a nearby building for the Rookie to eventually find. Unsure of Dare's fate, Buck and Romeo decide to scrap the mission, find their squad, and get out of the city.
Immediately after drop
The sound of the Slipspace rupture opening can be heard.
View opens on one of the Superintendent's cameras (location labeled as Lumumba) just as the shockwave from the Slipspace rupture passes through the city. The screen adjusts to the brightness, and the air is still full of blue particles from the rupture. From a camera below the Superintendent watches two SOEIVs drop in, one of them bounces off a building, deflects into a second and crashes upside down, the other pod goes straight behind the second building. The Superintendent zooms in on the first pod, its avatar showing a sad face.
Buck's hatch opens and he falls out of his pod.
Buck picks himself up, depolarizing his helmet. He begins to search his SOEIV.
He finally gets his assault rifle out.
A Phantom flies overhead. Buck looks up.
Buck polarizes his helmet and begins to move.
Another Phantom arrives in front of the plinth that Buck is currently on, and begins to descend.
Buck cocks his assault rifle.
The Phantom deploys a group of Covenant consisting of a large number of Unggoy and a pair of Jiralhanae. They soon notice the lone ODST and open fire. Buck soon eliminates the Covenant present. Advancing around a building, Buck comes across two Marines behind a destroyed Warthog.
In the corridors and balconies of the nearby building, Buck finds the corpses of many Covenant soldiers, namely Sangheili and Jiralhanae. Blood splatters, Spiker rounds and plasma scoring cover the walls and floors.
Using the advantage of elevation, and with support of the Marines, Buck surprises a patrolling Jiralhanae pack and neutralises them. More Unggoy and Jiralhanae with support from an Unggoy Heavy operating a plasma cannon attempt to stop the humans but they too fall. Buck moves up to an intersection with several roadblocks. More corpses of Sangheili and Jiralhanae litter the area.
The Covenant troops soon fall. If the player lingers around the door without opening it:
After opening the door Buck finds a group of Marines armed with silenced SMGs around a destroyed Warthog, taking fire from a large number of Covenant, including a number of Kig-Yar Snipers, soon getting killed.
If Buck goes left to the building, he will find a female Marine taking cover.
After a protracted battle in which Buck defeats a large number of Unggoy, Kig-Yar and Jiralhanae infantry, the ODST approaches a blast door on the other side of the area. Before he reaches it, the door opens and a pair of hulking Mgalekgolo charge through.
After a struggle, Buck manages to defeat the Mgalekgolo pair and he leaves through the now-opened blast doors. He arrives at Dare's location.
Dare's SOEIV comes into view, under attack from a trio of Unggoy.
After dispatching the Unggoy, he approaches her pod and tries to open the door.
Buck manages to shove the hatch off the pod, but it is empty. Suddenly, a Huragok pops out of the ground near Buck.
The tentacled alien gets closer to Buck, who falls over backwards, and a blue light appears from its helmet.
Buck sees Dare's damaged helmet in one of its tentacles.
Buck gets up, the dead Huragok starts to shake and starts to give off a high pitched whine, Buck dives for cover and it explodes, propelling Dare's helmet into the air. The Superintendent tracks the helmet.
The Superintendent finds that the helmet will be launched through a window.
The Superintendent's avatar shows a happy face. Buck walks up to meet Agu near the SOEIV. He picks up his assault rifle and holsters it.
Agu doesn't respond. Buck depolarizes his helmet and takes it off.
Agu depolarises his helmet.
Buck investigates a piece of the Huragok's armor, with Dare's stomach armor plate attached to it, stuck in a wall.
Agu shakes his head.
Buck puts his helmet back on, and the level ends. Screen fades to black.
