Take It Back!

Objectives:

• Follow Liberty Prime as he makes his way to the Purifier
• Reach the Project Purity Control Room
• Secure the Project Purity Control Room
• Activate Project Purity
• Project Impurity "Infect the Project Purity water supply...or not"

Head out to the courtyard and witness the birth of an amazing killing machine...in the name of justice! Liberty Prime is finally up and running, and ready to kick some serious Enclave tooty. You and the Pride are to support the hulking robotic giant as it lays waste to Autumn's hostile forces. Your destination is Jefferson Memorial, the site of Project Purity, but you can't Fast Travel there, so you must march in the shadow of the colossal robot. Prime is responsible for destroying the Enclave's energy fields leading into Purity. The hike there may very well be slow and steady, but for a purpose: to focus the Enclave's attention on Prime.

While Prime and the Lyon's Pride can surely hold their own and handle much of this final mission, help where you can until you reach the Jefferson Memorial Gift Shop entrance. You are about to reach the point of no return, so if you've got other places you want to be at in the vast Capital Wasteland you'd want to detour the mission now! Once inside the Jefferson Memorial, make your way to the Project Purity Control Room to face the gruff Colonel Autumn.

Colonel isn't too surprised to see you here. With high Speech skill, you can convince the Colonel to step aside and withdraw his forces. Otherwise, you're going to have to gun him down sooner rather than later. Start out by tossing a grenade to soften Autumn and his bodyguards, then pump them full of lead. This battle is made especially more easy if you've got the Alien Blaster or a weapon of similar caliber.

Following the battle, Sentinel Lyons joins you as the two of you listen to Dr. Li, who tells you that the Purifier must be activated, or everything we have been fighting for will be for naught. Sounds all gravy, except the person who chooses to activate it will likely lose his or her life due to exposure to the tremendous radiation. There are several ways to go about this, and all possible methods do lead to some sort of supreme sacrifice. You could play the hero card and elect yourself to go, order Sarah to go in your stead, or pretty much do nothing. Take note that the first two options are completed after inputting the correct code (216).

Congratulations! You beat Fallout 3! Now depending on what you did throughout the game you will generate one of numerous endings for yourself. The ending you get is influenced heavily by your Karma, your decision in Take It Back!, your race, and gender. There were a few other crucial choices that decided your end fate, as well, including-but not limited to-whether or not you sided with President Eden.
