Liberty Prime

Liberty Prime is a U.S. Army pacification robot. Standing at forty feet tall and armed with a variety of weapons, Liberty Prime is a nigh-unstoppable killing machine whose sole purpose is to destroy any and all "communists" (a label which it will humorously apply to anyone who opposes its masters, regardless of their actual motives).

Background
The original purpose of Liberty Prime was to aid American troops in the liberation of Anchorage, Alaska from communist China. Through the computer terminal at the foot of Liberty Prime, it is revealed that the project was commissioned by General Constantine Chase and was a joint effort between the U.S. Army, General Atomics, and RobCo. (He is, presumably, the "technological marvel" mentioned in the Brotherhood's faction profile, and the unknown super weapon referenced in one of the newspaper cuttings that appears in the game.) However, problems with the power system led to delays, and ultimately Anchorage was liberated by America in a much longer and more costly battle using their other secret weapon, the more successful and reasonably-scaled T-51b Power Armor.

Roughly two centuries later, Liberty Prime is put back into service by the Capital Wasteland Brotherhood of Steel after they find him in the basement of The Pentagon. Liberty Prime would finally be completed by the Brotherhood of Steel in 2277, after which the massive robot led a Brotherhood attack against the Enclave based at the Jefferson Memorial, humorously mistaking the Enclave troops for a Chinese invasion army and spouting anti-communist propaganda statements throughout the battle.

Liberty Prime requires a massive amount of power to operate, and the Brotherhood of Steel was long unable to power him properly even with the advanced tech discovered inside the Pentagon. With the aid of Madison Li, they eventually solve this problem. His large backpack holds a seemingly inexhaustible supply of nukes, similar in potency to a Mini Nuke but several times larger. He can remove and hurl these nukes at enemies like a quarterback throwing a pass. He is also equipped with twin head-mounted lasers which will kill anything in a single hit. His massive size and strength count as weapons too: he is endowed with strength befitting a forty foot tall robot, and can rip anything in his path to shreds... if he doesn't step on it first. He also appears to have an energy shield, as he can sustain massive amounts of damage and short out energy barrier fields by forcefully walking into them. Finally, to inspire his allies and demoralize foes, he constantly spouts anti-communist phrases (like most of the servitor/combat robots in the game, he seems unaware that any time has passed between 2077 and the present).

Interactions with the player character
He is first seen in the lab beneath the Citadel in his inactive state. The player can gain information about Liberty Prime as well as hear some of his dialogue by using a nearby computer terminal to initiate a dialogue test.

During the events of Take it Back!, the Brotherhood of Steel (with the cooperation of Dr. Madison Li) manages to reactivate the robot, who then proceeds to clear the way for the Lyons' Pride to the Jefferson Memorial, where he remains until the end of the game. Despite the sense of urgency imparted to the player to protect him in this mission, Liberty Prime is in no way endangered by the Enclave forces, and at his size moves so fast that keeping ahead of him is rather difficult. He is entirely capable of defeating the Enclave all by himself, and will do so quite enthusiastically.

During Broken Steel, Liberty Prime joins the player in the battle against the Enclave during Death From Above. After the Enclave initiates an Orbital Strike, Liberty Prime will crawl from the wreckage and initiate a self-destruct sequence to prevent his capture by the "communists". His head, both feet and what appears to be a forearm are later taken back to the Citadel. Similar to Deputy Weld, his head can be activated and he will say some of his anti-communist phrases, albeit scrambled and garbled. At the conclusion of the main quest line, Scribe Rothchild states that the Brotherhood will rebuild Prime, but it might take months to years.

Appearances
Liberty Prime appears only in Fallout 3.

Behind the scenes

 * Liberty Prime is humanoid in shape, and somewhat resembles the title character of the movie The Iron Giant, but possesses the head (and laser vision) of Gort from the 1951 version of The Day The Earth Stood Still.
 * According to an interview in 1UP Emil Pagliarulo denied any intentional relation between Liberty Prime and Optimus Prime. Pagliarulo admitted he could have made the reference subconsciously, as he sometimes is known to do.

Bugs

 * It is possible that Liberty Prime will have path issues on the first large bridge you cross, and get "stuck" requiring you to reload a save. Sometimes these path issues can be resolved by destroying the junked cars on the bridge, or by fast-traveling to the Citadel (only an option if you are out of combat). If he gets stuck behind a car simply blowing it up will work; however there is a possibility an Enclave Vertibird will crash in his path, in which case nothing but a MIRV will budge it. Sadly this makes all Brotherhood forces except Sentinel Lyons hostile towards you.
 * Liberty Prime will sometimes simply not move from his starting location.
 * The player can make Liberty Prime hostile to themselves by shooting at it for a while, but can freeze if too much damage is done, possibly because of the disruption to its routine.
 * Once you complete the Broken Steel add-on, you can find Liberty Prime's severed head in the Citadel, but at the same time you can find it on the ground at the Satellite Relay Station.

Quotes
Liberty Prime spouts a wide array of overly patriotic and anti-communist phrases, in a booming voice that can be heard at great distances (no doubt to inspire fear in his enemies). Many of the quotes are grandiose in nature and can be seen as comic relief due to the contradictory and hypocritical nature of them.

Following the destruction of Liberty Prime, he will still say some of his quotes but in a garbled manner.


 * "COMMUNISM IS A LIE."
 * "DEATH IS A PREFERABLE ALTERNATIVE TO COMMUNISM."
 * "COMMUNISM IS THE VERY DEFINITION OF FAILURE."
