Legacy ( video game ) Doctor Who : Legacy was a game released to the iOS , Android , and Facebook platforms in the wake of the 50th anniversary special . Initially billed as an adventure featuring the Eleventh Doctor at the crux of its events , it continued to update past his era ' s conclusion in 2013 , then transitioned to his successor , the Twelfth Doctor . As character licensing rights were obtained , the game gradually expanded to feature every direct incarnation of the Doctor . It allowed users to replay the events of several episodes of " Doctor Who " s 4th , 5th , 6th and 7th and 8th series , using — if they so wished — different combinations of Doctors , companion s , and featured guest stars than were present in the story as televised . Indeed , players could replay each episode however they wish , meaning that gameplay was different for all users , and even for each individual . Despite this , the cut scenes found in many of the levels that advanced the plot of the game always remained the same , regardless of which characters were on one ' s team or how many times the level had been played , or the player ' s overall progress . Due to this , although the game mechanics of various levels were different , the plot remained consistent for every user on every play through . It was also notable for featuring mentions and appearances of original characters from the expanded " Doctor Who " universe outside from the TV show , including Abslom Daak , Alice Obiefune , Gabby Gonzalez , Frobisher , Charley Pollard and Liam McShane , with more in the plans to be added . At launch , the game ' s story was meant as a simple means for levels to work backwards through the show ' s seasons , starting from Series 7 and working back all the way to " An Unearthly Child " . But with the massive increase in content out of sequence with the original approach ( including Series 8 and 9 , the classic series , and the Titan Comics publications ) , the story took on a more original turn , with specific chapters and several side stories made without direct reliance on single seasons of the show . Synopsis . Chapter 1 : The Sontaran Threat . The Eleventh Doctor and Vastra arrive in Cardiff on 16 October 1978 , discovering that the Earth has been prematurely invaded by the Sontaran s , who have acquired time travel and are rewriting the planet ' s , and the entire universe ' s , history . The Doctor determines that he must go back through his own personal timeline to defeat them , gathering friends and companions to help him , before its too late . Vastra summons Jenny Flint , and the three go to Hedgewick ' s World of Wonders during the Cybermen attack to find Porridge , to the Dalek Asylum for Rory Williams , and the Latimer Residence for Jagganth Daiki - Nagata , before moving on further through the Doctor ' s most recent adventures . They manage to find more companions and halt the Sontaran ' s operations , but along the way , they find massive paradoxes destabilising time and allowing events that never occurred to happen , such as encounters uniting the Doctors ' enemies , along with some events to occur out of sequence , such an encounter with the Silence . Many other skirmishes take place , resulting in Clara Oswald joining the team in 1875 Paris , Sam Garner from the depths of New York City , and John Riddell in a forest in Scotland . Stabilising the paradoxes leads to the Doctor ' s previous incarnations , including his Tenth , Seventh , and Sixth selves , being sent through time to join the team . The chapter closes out as the Doctors and his TARDIS team combat the Great Intelligence , in the form of a glowing transparent pyramid , through its activities in London 1892 , 2013 , and Trenzalore , uniting with the Eighth Doctor along the way , culminating in a confrontation in the Time Vortex where it calls upon Snowmen and the Ice Governess for defence , ultimately failing , after which they manage to find Jo Grant . Chapter 2 : Enter . . the Zygons ! Fending off an attack from a Sontaran Flagship , the TARDIS materialises in modern day London , only for the team to find themselves under attack by Zygon s , who have allied with the Sontarans and are being used as reinforcements against the Doctors and his companions . The TARDIS team presses on , going through the events leading up to the Doctor ' s " death " on Lake Silencio to continue stabilising time and combating the Sontaran / Zygon menace , continuing to gather allies along the way . More paradoxes also lead to the Third Doctor joining the team . But time is destabilising further , leading to battles against the Weeping Angel s over London , a Dalek invasion in 2024 , an army of Rorybots , and an " unholy alliance " between the Church and the Daleks . They also encounter a unique series of artificial paradoxes that appear to be the attempts of someone trying to reach them . The Doctors begin to formulate a plan , trusting in the ingenuity of humans and believing that ensuring the safety of creative and important individuals like Vincent van Gogh and Winston Churchill can limit the fractures in time being caused by the Sontarans . But after facing and defeating Sontaran Captain Vade the Defiant , they are told that forces greater than the Sontaran Empire are after them . Evading enemies from across the collapsing timesteam , the TARDIS team follow the trace of another artificial paradox that leads them into the edges of a time storm around December 25th , ensnaring them in a temporal hurricane of snowy weather . Finally reaching the paradox , the Doctors manage to reverse the polarity of the paradox ' s neutron flow , allowing Jack Harkness to reach them at last . He informs them of the entry of " an old friend " of theirs into events . Meanwhile , the First Doctor watches from his own TARDIS the full extent of the Sontarans ' plans , and to his horror , the fall of Sontar as an army of Toclafane , led by the Master , overwhelm the planet and its forces all across time at once . Chapter 3 : The Rise of the Master . The TARDIS team pushes through the time storm , confronting enemies the Doctors have fought previously at Christmastime . They realise Jack Harkness is right when they witness the Sontarans being decimated by Toclafane , as well as when they receive a message directly from the Master himself . They push onward to escape the storm , passing through the Doctor ' s future in Christmas and uniting with the War Doctor in the process . Once out , they continue running through time to evade the Master , going through through the early adventures of the Eleventh Doctor in the process . They find time to pick up some of Jack Harkness ' s allies such as Ianto Jones , and manage to come into contact with the Second and Ninth Doctor s . They ' re also plagued by the generation of bubble universes in the weakened timeline , which pull the the TARDIS into them as quickly as they ' re created . Observing their efforts , the First Doctor decides now is the time to join his future selves , uniting with them through a paradox surrounded by Adipose . Not giving up on catching the Doctors , the Master continues to pursue the TARDIS team through both his Toclafane and his own past selves . As the Doctors evade the Weeping Angels in the caves of Alfava Metraxis , they ' re confronted by , but the TARDIS team manages to outmatch him . Later , the Master uses his TARDIS to attack the Doctor ' s through the Time Vortex , but is again bested , leaving a Sontaran Flagship in his wake that forces the TARDIS to materialise on Krop Tor in the middle of the Beast ' s awakening . Not long after , they face in a skirmish with the Toclafane in Tarminster , but would once again manage to escape . In what is called " The Hunt for Greyhound One " , following a breach of Toclafane into the TARDIS interior , the Doctors realise that they need an army to fight the Master ' s forces , and for that , they need a great military leader . The decision to find the Brigadier is made , but to reach him through the weakened timestream , the need to build a specific machine to summon him . Retrieving metal casing from a Silent ship , gears from " Starship UK " ( where they acquire a Winder ally from landing fifty years after freeing its star whale ) a sentient lens in the form of the melted Ice Governess , and harnessing the power of the Doctor ' s tomb on Trenzalore , they manage to build the machine and retrieve the Brigadier , fresh from his days alongside the Third Doctor . But the reunion is short - lived , as their actions summon " time sundered " Whisper Men that are much more dangerous than before , forcing the team to flee back to the TARDIS . They make a blind jump through time to escape , ending up at Auderly House during the World Peace Conference , where another paradox leads to the Fifth Doctor joining the team . Chapter 4 : Betrayal and Redemption . Now aided by the Brigadier , the TARDIS team determines they need a weapon that can specially hurt the Toclafane . Martha Jones and the Tenth Doctor remember a diary Alison Docherty wrote on combating them , and the Doctors conclude that it very well could ' ve ended up through the alternate timelines at the Library . But before they can head there , the TARDIS is pulled into the relative future , bringing them to Sherwood Forest in the middle of the Sheriff of Nottingham ' s fight with the Twelfth Doctor . The TARDIS team helps defeat him , and the Eleventh and Twelfth Doctors are shocked at each others ' presence before the team returns with him to the TARDIS , which now takes on the Twelfth Doctor ' s console room design . Now up to speed , the Twelfth Doctor helps the team fly the TARDIS to the Library , fighting through paradoxes along the way that summon the Fourth Doctor , uniting all thirteen of his incarnations . But as the TARDIS materialises , the Doctors vanish , and the doors open to reveal Professor River Song . The older and more experienced River takes the lead , guiding the companions through the Vashta Nerada into a chamber containing a wealth of books and material pertaining to the Doctor , where Docherty ' s diary is found . Its information proves immediately useful as the team fends off the Toclafane , the Saxon Master , and as they return to the TARDIS . The Doctors reappear as the team returns , explaining that a temporary snap in the timelines was to blame , and that the TARDIS should be able to prevent a more serious repeat . With the information from Docherty ' s diary , the Doctors determine that a tellurian transformer from a Cyberman info - stamp could be plugged into the TARDIS and be able to send a shock through time to disable all Toclafane . As its a rare piece of technology , the Doctors split up to find it . The First Doctor travels to Antarctica and checks the invasion force from the Snowcap invasion for an infostamp , with no luck . As the Twelfth Doctor , the younger River Song , and Clara Oswald search the 3W Institute , they ' re confronted by Missy , who summons a Cyberman army and a CyberKing to stop them . River retreats to the TARDIS to secure it while the Doctor and Clara utilise Bessie to escape the CyberKing , which gives chase through the streets of London . After evading its missiles and other attacks in a lengthy pursuit , the Doctor has River land the TARDIS into the ground with enough force to create a chasm in the street , which the CyberKing falls into . The TARDIS team departs London , hoping the others have found an infostamp . Bigger on the Inside . Prologue . Some time after all the Doctors have united , a strange metal spikes shoots into the TARDIS through the Time Vortex and pierces the console , spreading a virus that leaves the TARDIS in inner chaos . As it struggles against the infection , the TARDIS ' s architectural reconfiguration system starts morphing the interior into places it has been previously , recreating enemies the Doctor had fought before . The TARDIS ' s perception filters are also affected , resulting in the Doctors and companions being made to perceive themselves and the TARDIS as a simplified , pixelated version of their usual appearances . As the TARDIS ' s defences are overwhelmed , something then relocates the Doctors and companions into separate version of the console room . The Tenth Doctor finds himself alone in the Twelfth Doctor ' s console room , defending himself from Clockwork Droid s , before reuniting with Amy and Rory . They defend themselves against Judoon until the console room morphs into the Beast ' s prison . Running off to force the interior to change again , they manage to morph it into the Farringham School for Boys , where they have to face off against the Family of Blood . Meanwhile , the First Doctor , in another version of the Twelfth Doctor ' s console room , manages to find Jack Harkness and Porridge before the interior morphs into Antarctica and pits them against the Cybermen ' s invasion of Snowcap . Chapter 1 . The First Doctor , Jack and Porridge continue to fight the Cybermen , the CyberKing , Snowmen , the Ice Governess and Reaper s . After defeating all of these , they face off an paradox , and continued to search for the TARDIS ' s console room . Meanwhile , the War Doctor and Cinder encountered the Cloister Wraith s and Weeping Angel s down on a room which looked like the Capitol . After they faced more Cloister Wraiths , Cybermen and Daleks , the General appeared . From there , they went onto another room , which recreated the Diner , where Slitheen and the Empty Child awaited . They kept moving , searching for the console room . The three entered the console room , where Polly , Ace and Sarah Jane greeted the Doctor . He , however , realised they were Zygons . After the Zygons were defeated , the Doctor and his companions moved on . On another part of the TARDIS , the Eighth Doctor and Josie Day met Grace Holloway . On a room that looked like San Francisco , they fought Sandminer robot s and time distortions . They found a door , which led to a malfunctioning TARDIS console . The Doctor was able to fix it with his screwdriver , and the trio moved on to the next room . That room resembled the Victorian London , where they faced Fendahl een . After defeating them , they kept moving . The next rooms looked like Tombstone , Vortis , a castle where Ice Warrior s , Judoon s , Scarecrow s , Ood s , more Weeping Angels and paradoxes , but they managed to get through them . Then , the War Doctor . the Eighth Doctor , Cinder , the General , Josie and Grace found themselves in the same room , where several Reapers appeared . The Doctors ' companions held the Reapers back , while they went searching for the tertiary console room . On their way , they met the Sycorax , Cybermen , Ice Warriors and a Dalek , until finally reaching the tertiary room . The War Doctor started remembering events from the Time War , when he confronted Rassilon about time distortions , and was sent along with Asmuth to investigate and destroy their cause . Four different versions of Asmuth accompanied the Doctor through Estragil , where they faced Daleks and Reaper s . During a fight against the Daleks , one of the versions of Asmuth , nicknamed by the Doctor as " Blue " died . Later , " Pretty Boy " , another version of Asmuth was also hit by a Dalek and perished . The Doctor went on through the city with the remaining versions of Asmuth , " Green " and " Phyllis " , until they were both hit by the Daleks and died . Alone , the Doctor continued his path , until he found the cause of the time distortions , a great beast that could swallow an entire Dalek fleet . Then , the General arrived with a few gallifreyan soldiers , but the Doctor advised them not to fire at the creature , because not even the Daleks had a chance against it . They retreated , going back to the Capitol . Sonic Adventure . Following the Cyber - King ' s defeat , the Master ' s incarnations meet over the failure of Missy ' s plan , during which she and reveal their next move . They use a machine to attack the TARDIS and dematerialise the Doctors ' sonic screwdrivers , as well as all the sonic devices carried by his companions , scattering them through time . However , the attack missed the First Doctor ' s signet ring , which is capable of many sonic feats without using the technology of the screwdrivers . With this as a tool to rediscover the missing devices , the First Doctor , joined by a team made up of Jack Harkness , Mickey Smith , Jo Grant , and River Song , set off through time on a quest to retrieve the team ' s sonics .
