Liberty Prime is a formidable combat robot that is being tinkered with in the Brotherhood of Steel's laboratory. Its original intent was to liberateAnchorage, Alaska, from the Red Chinese back in 2072. A mixture of patriotic propaganda messages and incredible firepower ensured victory!
Roughly two centuries later, Liberty Prime was finally salvaged and brought into service by the Brotherhood of Steel after they discovered it in the basement of the destroyed Pentagon. The Brotherhood was able to modify Prime's targeting system to perceive Enclave forces and super mutants to be Chinese communists.
Liberty Prime required a massive amount of energy to operate. Subsequently the Brotherhood of Steel was unable to provide the necessary amount of power, even with the advanced technology salvaged from inside the Pentagon. Eventually, with the aid of Dr. Li, the Brotherhood of Steel solved the problem.
Liberty Prime was the Brotherhood's trump card against the Enclave, and was revealed when it marched on Project Purity where it was used to effortlessly destroy 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 of Steel and, though it would take months or years to do so, the Brotherhood set about rebuilding and upgrading it.
Liberty Prime fires dual, head-mounted energy beams, which are similar to shots fired from a Tesla cannon. The beams can kill multiple Enclave soldiers with a single shot. Its backpack holds a seemingly inexhaustible supply of explosives that it hurls at enemies with unerring accuracy. These munitions detonate on contact, in a manner very similar to a mini nuke, apart from having several times the explosive power. Liberty Prime's massive size and strength count as weapons too, as it can crush or rip to shreds anything in its path, if it doesn't blast them to bits first. It can sustain large amounts of damage, and defeat energy barriers by walking into them, although it will sometimes grab them and rip them down. Finally, to inspire its allies and demoralize foes, it constantly spouts anti-communist phrases as well as declaring that "American democracy cannot be defeated". Like most of the robots in the game it seems unaware that any time has passed between 2077 and the present or, more accurately, that any cataclysmic or world-changing events have transpired.
Take it Back!: The Brotherhood of Steel, with the help of Dr. Li, manages to fix the power issues with the robot. With the pressing need to reclaim Project Purity, Elder Lyons orders Prime deployed without proper testing. Liberty Prime 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 Memorial's entrance, after taking down the force field surrounding it. The giant robot will then remain 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!.
Liberty Prime is first seen in the lab beneath the Citadel in its 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.
In an e-mail from RobCo Industries to the US Army, it is revealed that although there are power management issues, it may still be possible to send Liberty Prime to Anchorage in time for the attack, although it is only possible if the Army were to disable all of Prime's weapon systems. Later in the e-mail, it is proposed that "Maybe he could just step on them?" instead.
If you watch Liberty Prime as it is being lifted out of the Citadel lab, Liberty Prime will hit the wall of the Citadel, subsequently causing a loud "thud" sound and dislodging some pieces of the wall.
Although the Lone Wanderer can't kill Liberty Prime, it's possible to cause it to turn hostile towards the Lone Wanderer, in which case it will eliminate them in a matter of seconds.
Although you may hear it make comments about the liberation of Anchorage, Liberty Prime never actually appears in, or is mentioned in the Operation: Anchorageadd-on as it was not completed in time.
Following Liberty Prime's destruction during the attack on the Enclave-held Satellite Relay Station, it reappears after the quest "Death From Above" within the Citadel, although it is in pieces. Despite the player being able to scour the wasteland for cameras and other equipment such as sensor modules in order to rebuild it, Liberty Prime is never repaired during Fallout 3.
After Broken Steel is completed, you can find Liberty Prime's head on the table in the Citadel lab. However, upon returning to the Satellite Relay Station where he was destroyed, you can still find his head, despite it being in two locations.
Although it is said that he is programmed to attack super mutants he will not attack Fawkes a super mutant companion.
Many of its quotes give reference to '50s and '60s anti-communist slogans, made to be more specific to China. Appearing below is a list of five quotes, randomly selected by the wiki:
"Liberty Prime is online. All systems nominal. Weapons hot. Mission: the destruction of any and all Chinese communists."
Liberty Prime throws football-shaped mini-nukes as if it were a quarterback. This pays homage to "The Nuclear Football", which is a term used to refer to the briefcase containing the launch codes for America's nuclear arsenal, with the president as the football's "quarterback".
ps3pcxbox360 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.
ps3 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.
ps3xbox360 If you manage to get far enough ahead of Prime when it is attacking Enclave forces, it is possible for the player to be killed by its attacks.
ps3 If you manage to get too far ahead of Liberty Prime before he disables the first "force field" he may stop walking across the first bridge after shutting down the first "force field."
