Lone Wolf/Walkthrough

Overview
This is the final level of Halo: Reach, in which Noble Six dies at the end, no matter how skilled the player is. The objective is therefore to survive for as long as possible. With the right combination of weapons and equipment, it might just be possible to survive indefinitely...

There'll be Another Time... (Rally Point Omega)
The objective is simply to survive for as long as possible. Here are some tips:
 * Detach both machine gun turrets and put them in the building that's directly in front of you in the beginning. It's the one with Armor Lock clearly visible.
 * Exit the building through the other side, swapping the DMR with the Assault Rifle.
 * Pick up the Shotgun, both Sniper Rifles, and the Drop Shield. Go back to the room you put the turrets in.
 * Use the Sniper Rifle to headshot Elites from a distance, and destroy the Wraith with the Spartan Laser when you get the chance.
 * When the Sniper runs out, swap it for the DMR.
 * When the Elites converge on your position, pick up the turrets and gun them down.
 * When your turrets run out, switch to your Shotgun. Elite Generals should start appearing at this point.
 * Pick up an Energy Sword when you get the chance, and swap it for a fresh sword as often as possible.
 * Deploy your Drop Shield whenever your shields are running low. You'll have your motion tracker for the entire level, and it is very important that you keep an eye on that.
 * Don't forget to use the health pack that's in the same room when you need it.

Trivia
There's an exploit allows you to survive indefinitely without doing anything. Just crouch in the corner of the Armor Lock room, behind the three crates. If the crates are positioned correctly, Elites will not see you.
