The Eternity Clock ( video game ) The Eternity Clock was the first of a three - part series of games for PlayStation 3 , PS Vita , and PC . It could be played by one or two players . The one - player option switched between the characters of the Eleventh Doctor and River Song . The two - player option had both characters playing simultaneously . Synopsis . Rogue time corridor s are opening all over London , connecting Elizabethan , Victorian , modern day and future London . It ' s up to the Doctor and River Song to investigate and close these corridors - a process not made easy by the sudden appearance of Cybermen , Dalek s , Silurian s and the Silence throughout history ! Plot . Onboard the TARDIS , the Doctor struggles to navigate a temporal maelstrom . He lands on Earth . However , the TARDIS appears in a bad way . The instruments confirm the time storm covers the planet . The Doctor exits to find himself in the Bank of England in the modern day . When the TARDIS vanishes in a flash of light , he is trapped . On the advice of a psychic paper message from his future self he uses gold bars to smash through a grate into the Victorian - era vaults under the bank . He finds a perception filter he recognises as his own work . He disables it , revealing a sewer entrance . However , the passage below is blocked by a gate requiring someone on each side to open . At the Stormcage Containment Facility in 5145 , River Song gets a phone call . The Doctor needs her help ! She escapes from the Facility . Once clear of its Tesla binding field , she uses her vortex manipulator to travel to modern day Earth , where she frees the stranded Doctor . They go through the old tunnels , trying to reach the surface . They soon find Cyberman storage units which begin releasing their occupants . The Doctor and River flee through the tunnels to reach a Bank of England lift that lets them enter the tunnels of the London Underground . The Cybermen pursue them , but the pair seal them off behind a set of large doors . In an area devastated by a gas explosion , the Doctor and River find an encampment of humans , refugees from the Cybermen who are converting people en masse . Before the pair can reach the surface , the Cybermen find a way into the area through more train tunnels . River and the Doctor electrify the rails , blocking their access . Ascending to the surface , River and the Doctor find the streets empty . A dormant time corridor , caused by the raging time storm , is near . With the construction site blocked by road collapse from the gas explosion , they go into an adjacent office building . They find another time corridor , which the Doctor identifies as leading to 1892 . They find a heavily guarded Cyberfactory ship on the other side of the office and the Doctor formulates a plan — he will travel through the time corridor , which has activated and alter the plans for the gas pipes in the past so the explosion takes place elsewhere . With the road traversible , they can enter the building site , use its crane to get on top of the office and drop into the unguarded Cyberfactory . The Doctor travels through the corridor with River ' s vortex manipulator and comes out in a textile mill . He makes his way outside and then underground . A mysterious figure dashes over the rooftops . Beneath the streets , he finds the under - construction pipes , alters the plans and returns through another time corridor to the present . Meanwhile , in the present , the Cybermen have entered the office block to investigate the energy from the corridor ' s use . Their forcible entry activates the building ' s security measures , trapping River inside . She tricks the Cyberman patrols into breaking open the office ' s security booth . She deactivates the barriers , allowing her to go out . She and the Doctor rendezvous and ascend the construction site , using a girder held by the crane to cross onto the office ' s roof . With the Cybermen still inside , the Doctor and River return to the street in a window - cleaning cradle and break into the Cyberfactory , intending to disable the Cyber - Planner inside . They follow the Planner ' s command signal towards the centre of the ship , but are forced to flee as squadrons of Cybermen are revived to pursue them . They eventually reach the ship ' s thermionic core , where the Cyber - Planner is located . River notices a mysterious object suspended near the Planner , which the Doctor identifies as having a huge temporal signature and broadcasting time distortion beam . He and River split up to reach control panels at the top and bottom of the core and use them to overload the thermionic power source to destroy the Cyberfactory . They escape through a newly opened time corridor , taking the strange artefact with them . After navigating through the corridor , they find themselves in the TARDIS . The Doctor connects the artefact to the console and finds it is responsible for generating the time corridors . The object is just one of four trying to speak with each other across time . They leave the TARDIS near London Bridge in 1561 , but the time corridor through which the ship appears immediately disappears . To leave they lower a drawbridge to access two other time corridors . Although they enter separate corridors , both arrive again in the TARDIS . The Doctor realises the ship has moved to the heart of the time storm to stabilise itself . The corridors lead to the TARDIS because they are being pulled in by the maelstrom . The ship also detects a signal hidden in the time storm . The Doctor decides to investigate it . They exit the TARDIS into 1561 again , but soon notice that tally marks are appearing on the walls around them . In London in 1892 , a Silurian warrior stands over the body of a policeman . The Doctor awakens , confused . He finds the sonic screwdriver and psychic paper gone , River ' s blaster and hallucinogenic lipstick in their place . He notices strange pipes carrying a green liquid on a nearby building . A 16th century statue hides the psychic paper , showing a message from River : the Silence have separated them across time and the Doctor must follow these messages to find her . In the building with the odd pipe the Doctor finds more pipes guarded by Silurian warriors . He also spots the sonic screwdriver on a statue salvaged from an old church , but the way to it is blocked by hot steam . He leaves the building and goes into the sewers beneath the streets . They are riddled with the Silurian piping . Evading guards , he finds controls to shut off the steam and returns to collect the screwdriver . On the advice of another psychic paper message , the Doctor heads back into the sewers . He uses the sonic screwdriver to access the same vault system he passed through beneath the modern day Bank of England , where he finds a perception filter hiding a doorway . Deactivating it , he reveals an old crypt , where River lies in a stasis field . In 1561 , River wakes to find her equipment gone and the Doctor ' s psychic paper in their place . A message on the paper from her future self tells her the Silence have separated the Doctor and her through time . She soon comes across a doorway , but the corridor it leads to seems too big compared to the building ' s exterior . River deactivates a perception filter , revealing a doorway which she recognises as leading to a Silence facility . Unable to get through , she leaves to find the sonic screwdriver in the nearby St . Christopher ' s Church . River uses the sonic to open the door into the Silence complex . Inside she finds them controlling temporal energy somehow and carrying out experiments on stasis field technology . She realises they are drawing the power they need from elsewhere , along conduits leading towards St Paul ' s Cathedral . She makes her way through the facility and steals the stasis field generator they are using . Now done with the Doctor ' s things , River hides the psychic paper and screwdriver on statues , then enters the church crypt . Disguising the tomb entrance with the perception filter from the Silence base , River activates the stasis field generator , allowing her to wait out the centuries in stasis until the Doctor finds her . In 1892 , the Doctor deactivates the stasis field generator , waking River . He sets up the perception filter where he found it in the modern day and they return to the sewers . They work together to access an area sealed with a Silurian door , allowing them to reach transport discs that lead underground . The Doctor grows concerned that time is wrong - the Silurians never attacked the surface world in the 19th century . In the underground Silurian city , the purpose of the pipes becomes clear - they are pumping deadly toxin into the city above and the entire system is being powered by an artefact similar to the one that the Cybermen had . The leader of the Silurian city , Vekkis , confronts them , and the Doctor forms a plan : he will reactivate walkways from the cavern ' s central column , allowing River to manually divert coolant , rather than toxin , into the pipes to the surface . Working together , they eventually flush all the toxin , then flee through a new time corridor , taking the artefact with them . After navigating through the corridor , they arrive back in the TARDIS , where the Doctor adds the new artefact to the other one . As the object begins ticking like a clock , River has a brainstorm ; it is an Eternity Clock . There are notes in her diary which she has no memory of ever making on one . The Doctor begins to understand the Clock can rewrite history . The notes in the diary are ' residue ' from an encounter erased from River ' s timeline . In addition , the Clock seems to be cataloguing all of time , ordering and recording events like a ' hard drive ' . The Doctor and River next travel to 2106 , where the New Dalek Paradigm has invaded and destroyed London . The Doctor realises the Daleks have put most of London in a time lock , rendering it unreachable . River states that , back in 1561 , the Silence had a laboratory that could contain a time capsule . Taking turns with the vortex manipulator , the Doctor and River travel back to 1561 and infiltrate the Silence stronghold located in the church . They find the time capsule , which is disguised as the church steeple . The Doctor begins to hotwire the alien tech ; however , the Silence arrive and try to fight them , forcing River to kill them to keep them off the Doctor . Once the time capsule is hacked , a third piece of the Eternity Clock is obtained , and the time capsule flies off into the time vortex . The capsule crashes in the centre of the Dalek stronghold , which is the same office building the Cybermen invaded in 2012 . They sneak past the Daleks and into the Dalek Command Node . A ten - minute timer begins - the Doctor and River have to make their way to the flag ship before the alarm goes off . The Doctor , piece by piece , deactivates the controls to the time lock , then activates the Dalek transmat which sends them up to the Dalek Flagship . Within the flagship , the Doctor realises that the Daleks are using the Eternity Clock to make the time lock bigger , pushing it out until the entire planet is locked and under control of the Dalek Empire ; once they perfect the technology to time lock entire planets , they would be unstoppable . The Doctor and River take an elevator through the ship , past the Dalek armies , to the chamber of the Dalek Emperor , who states that the Doctor ' s time is over and the Daleks are " the new lords of time " . The Doctor and River formulate a plan ; River will blast the Emperor Dalek ' s eyestalk , stunning it and keeping it from attacking , while the Doctor reverses the polarity of the Dalek Matrix , which deactivates the time lock once and for all , and releases the final piece of the Eternity Clock from its force field . Once the Doctor has the piece in his hands , a new time corridor opens up , taking the Doctor and River back to the TARDIS , and wiping the alien invasions which were not supposed to happen from history . Back in the TARDIS , the clock reassembles itself , and the time storm stops . However , the Doctor ' s equipment picks up a temporal signal - one that the interference from the fragmented Eternity Clock was drowning out , and one that the clock is now trying to track down . River realises that the Eternity Clock and the TARDIS are synching together , and that when they do , the TARDIS will travel to find that point in time . They barely have time to state this before the TARDIS takes off on its own ; unable to stop it , the Doctor and River cling to the controls and yell " GERONIMO ! " Aditional voices for international versions Crew . " to be completed " Story notes . As production on this game predates the War Doctor ' s debut in the 2013 television story " The Name of the Doctor " , the entries in River Song ' s diary involving past incarnations of the Doctor do not refer to him . Following the broadcast of " The Name of the Doctor " , in the 2015 television story " The Husbands of River Song " , it is revealed the possibility that River Song has met the War Doctor as well when his face is included among the photos of the Doctor she owns .
