Halo 2 Mission 5: Metropolis

Metropolis is the fifth campaign level of Halo 2. It is the first level where the player is able to drive the Scorpion Tank and the first level with Wraiths and Banshees. Metropolis is one of two levels where the player can acquire the Gauss Warthog (the other being Quarantine Zone). It takes place in New Mombasa, and starts as soon as the player emerges from the highway tunnel that was the last part of Outskirts. In this stage, the Master Chief and two Marines must battle across a long bridge guarded by Covenant forces and another but shorter tunnel than the one at the end of Outskirts. After that, there is a small park, where another Marine-controlled Warthog lurks, and an open urban area with Wraiths, before going onto catwalks attached to buildings in order to attempt to board the Protos-pattern Scarab and take out the Covenant piloting it.
