"Reclaim the city. Make a hole.
The Storm is the fifth campaign mission of Halo 3.
It begins with a UNSC Warthog convoy moving to Voi, its objective to punch through the Covenant Loyalist Anti-Aircraft defenses that surround the supposed Ark and allow Lord Hood's small fleet of ships passage to the Prophet of Truth's fleet in order to kill Truth and stop the firing of the Halo rings. UNSC Marine forces, led by SPARTAN-117, fight through several pitched skirmishes through the industrial zone of Voi.
After breaking through the industrial area, SPARTAN-117 meets up with a group of approximately five Mongoose ATVs and commandeers one with a Marine riding 'pillion' using a M41 Rocket Launcher.
They immediately engage a squadron of Anti-Air Wraith tanks to secure a landing zone as Brute Choppers and Ghosts attack. The Covenant are being continually reinforced by Phantoms.
Hornets and Banshees fly above, vying for control of the skies. Although they manage to take the landing zone, the victory ends up being short-lived as a Scarab arrives to crush the UNSC forces.
After John-117 destroys the massive walker, remaining UNSC forces prepare to push into a Brute-controlled warehouse.
