Liberty Prime

Liberty Prime is a unique U.S. Army robot that was found, and brought to working order by the Brotherhood of Steel in the year 2277.

Background
Liberty Prime's original purpose was to aid American troops in the liberation of Anchorage, Alaska from Chinese occupation in the year 2077.

The computer terminal in the Citadel Laboratory, to the right front of Liberty Prime's feet, reveals the project was commissioned by General Constantine Chase as a joint effort between the U.S. Army, General Atomics International, and RobCo Industries. However, problems with the power system led to delays, so that Anchorage was ultimately liberated in a much longer, as well as costly battle using the US Army's other secret weapon: the T-51b power armor.

Roughly two centuries later, Liberty Prime was finally pressed into service by the Brotherhood of Steel after they discovered him in the basement of the destroyed Pentagon. The Brotherhood modified its targeting system to perceive Enclave forces and super mutants to be Chinese communists.

Liberty Prime required a massive amount of energy to operate. Initially the Brotherhood was unable to power him properly, even with the advanced technology discovered inside the Pentagon. Eventually, with the aid of Doctor Li, the Brotherhood of Steel solved the problem.

Liberty Prime was the Brotherhood's trump card against the Enclave, and was revealed when he marched on Project Purity where he was used to effortlessly destroyed the Enclave defenders entrenched there. For two weeks afterward, Liberty Prime fought battles against the Enclave, but was eventually destroyed by an orbital warhead bombardment at the Enclave-held Satellite Relay Station. Liberty Prime's remains were recovered by the Brotherhood and, though it would take months, or years to do so, they set about rebuilding, as well as upgrading him.

Liberty Prime fires twin, head-mounted energy beams, similar to shots fired from aTesla cannon, and can kill many Enclave soldiers in a single shot. His backpack holds a seemingly inexhaustible supply of explosive "footballs" that he hurls at enemies with unerring accuracy. These munitions detonate on contact, in a manner similar to a mini nuke, but with several times the explosive power. His massive size and strength count as weapons too, and he can crush, or rip to shreds anything in his path. He can sustain large amounts of damage, and defeat energy barriers by walking into them. Finally, to inspire his allies, and demoralize foes, he constantly spouts anti-communist phrases and declares that American democracy cannot be defeated. Like most of the robots in the game, he seems unaware any time has passed between 2077 and the present, or more accurately, that any cataclysmic, or world-changing events have transpired.

Quests

 * Take it Back!: The Brotherhood of Steel, with the help of Dr. Li, manage to fix the power issues with the robot. With the pressing need to reclaim Project Purity, Elder Lyons orders Prime deployed without proper testing. The giant robot makes its way to the Jefferson Memorial, while destroying Enclave energy barriers, vertibirds, and troops while en route to the Memorial. Once there, Liberty Prime assists the Brotherhood in guarding the building's entrance. It remains there for the duration of the quest.
 * Death From Above: Liberty Prime joins the Lone Wanderer in the assault on the Satellite Relay Station, an Enclave base located beyond the Rockland Car Tunnel. After the Enclave hits Prime with an orbital strike, Prime crawls from the wreckage and initiates its self-destruct sequence to prevent being captured by the "communists". Its head, feet, and what appears to be a forearm are taken back to the Citadel. Similar to Deputy Weld, its head can be activated, which will cause it to play back some of its anti-communist phrases, although they sound much more garbled than they are during Take it Back!
 * Getting Ready for Prime Time: At the conclusion of Broken Steel's main quest line, Scribe Rothchild vows the Brotherhood will rebuild Prime, although it may take months, or even years. He then asks for the player's help in scavenging sensor modules and cameras to assist in the rebuilding process.

Other interactions

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

Behind the scenes

 * 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.
 * The GECK lists a cut quest called "Infiltration" which was situated between The American Dream and Take it Back! and had the player stealing a power source from Rivet City to power Liberty.

Bugs

 * Liberty Prime often gets stuck. Although the most common places for this glitch is on the left side of the highway when heading to retake the Purifier at the Jefferson Memorial, and on the first large bridge you cross.
 * Liberty Prime may launch into the air and remain there. The best way to solve this is to wait (real time). If this fails, the player may need to reload the previous auto save.
 * Once you complete the Broken Steel add-on, Liberty Prime's severed head can be found in the Citadel, while at the same time it can also be found on the ground in front of the Satellite Relay Station.
