Metropolis

Summary
Metropolis is the third playable level in Halo 2. 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. 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 Scarab and take out the Covenant piloting it.

{a marine sitting on the ground watches as Master Chief approaches, MC walks over to another marine}

Marine 1: "It blew right through us." {they watch the Scarab stomp through the city} "50-cal, rockets, didn't do a thing."

{a Pelican drops a Scorpion, Johnson gets out, MC and marines walk over}

Sergeant Johnson: "Where's the rest of your platoon?"

Marine 1: "Wasted, Sarge."

Marine 2: "And we will be, too, sir, if we don't get the hell outta here."

Sergeant Johnson: "You hit, marine?"

Marine 2: "Uh, no, sir."

Sergeant Johnson (Easy): "Then, listen up! You had your chance to be afraid before you joined my beloved Corps. But to guide you back to the true path, I brought this motivational device. Our big green style cannot be defeated!"

Sergeant Johnson (Normal): "Then, listen up! The Chief is gonna jump in this tank, roll across the bridge, and blow up any inhuman son of a bitch dumb enough to get between him and the Prophet of Regret. Pull yourself together! Because you're going with him."

Sergeant Johnson (Heroic): "Then, listen up! When I joined the Corps, we didn't have any fancy-shmancy tanks. We had sticks! Two sticks! And a rock for the whole platoon. And we had to share the rock. Buck up, boy, you're one very lucky marine."

Sergeant Johnson (Legendary): "Then, listen up! Usually the good Lord works in mysterious ways, but not today. This here is sixtysix tons of straight up, H-E-spewing divine intervention! If God is love, then you can call me Cupid."

Marine 1: "What about that Scarab?"

Sergeant Johnson: "We've all run the simulations, they're tough, but they ain't invincible. Stay with the Master Chief, he'll know what to do."

Marine 1: "Yes, sir, sergeant!"

Cortana: "Thanks for the tank. He never gets me anything."

{Johnson climbs back on the Pelican, readys a machine gun}

Sergeant Johnson: "Oh, I know what the ladies like."
