Lost in Time (video game)

Doctor Who: Lost in Time was a licensed 2022 Doctor Who video game released for iOS by Eastside Games.

The game was broken down into chapters with individual titles. The narrative, involving a mysterious temporal anomaly messing with the Doctor's memories, featured multiple Doctors and companions. However, it was not a conventional multi-Doctor stories: the different Doctors never met, with K9, newly-fitted with a vortex manipulator circuit, acting as a go-between. It was an idle game, meaning gameplay consisted of little more than accumulating experience points via repetitive actions to unlock the next cutscene.

Episode 1: Lost in Time
When the TARDIS is forced to make an emergency landing to the "nearest familiar spot", the Thirteenth Doctor and Yasmin Khan land in the Third Doctor's UNIT HQ laboratory. Making matters worse, the Doctor has no memory of the place, even though, by design, it should be familiar to her. The Doctor and Yaz are met with K9, who seems to understand more about the situation and explains that UNIT HQ passing through a black hole's event horizon created a "dimensional Waypoint", charging the building with Vortex Energy. The Doctor tells K9, who is able to move through time, to contact her other incarnations about the temporal crisis, and to pass on the message "Memory gaps. TARDIS is stuck. Send Vortex Energy!", collected from other Waypoints across space and time.

Indeed, elsewhere in time and space, others have been affected by the crisis. The Tenth Doctor's TARDIS has been pulled off-course to ancient Skaro, with Sarah Jane Smith aboard, and has gotten stuck there. Sarah is able to remember her past encounters with the Daleks, unlike the confused Doctor, but despite his mental fog, the Doctor is able to remember K9's message: the Dalek City has also become a Waypoint, from which he must draw vortex energy to revive his TARDIS.

At UNIT HQ, the Thirteenth Doctor succeeds in drawing sufficient power to unstick the TARDIS. However, she is worried that the unrefined vortex energy might cause power surges in the TARDIS console. Yaz jokingly advises her to "reverse the polarity" using the sonic screwdriver, a phrase she's heard the Doctor use before; it turns out to work, but to Yaz's surprise, the Doctor has no memory of using the phrase previously. The Doctor, Yaz and K9 get into the TARDIS and successfully take off, though they suspect they'll have to do it all again every time they want to take off again until such a time as the crisis is resolved.

Episode 2: Emergence of the Daleks
The Thirteenth Doctor's TARDIS lands. As predicted, K9 Mark IV notes that the trip depleted her reserves of vortex energy. K9 sends a message through time to the Tenth Doctor, still stuck in the Dalek City, to tell him that one of his future incarnations has freed themself and will try to send him spare vortex energy if they can. In the meantime, Sarah reminds the Doctor that, if his fourth incarnation's statement that the Daleks had been delayed for "a thousand years" was accurate, the Daleks shouldn't be free yet in the time-zone where they've ended up. Indeed, they hear Dalek voices in the distance.

Meanwhile, the Thirteenth Doctor and Yaz venture out into a marketplace where they meet Sil, who sells them a way to absorb vortex energy in larger increments. K9 then transports himself to the Dalek City. He proves a great asset, helping to automate the vortex energy collection process, and assures the bipeds that he is no danger from the Daleks: the smooth metal floors of the City are as ideally suited to his movements as to the Daleks', and he is faster. The Doctor additionally explains to Sarah that "since you last met", K9 has been upgraded, notably being given an internal vortex manipulator and a Temporal Positioning System. This is how he's been moving and communicating through time even with the Doctors' TARDISes partially disabled.

While K9 handles the vortex-energy collection, the Doctor and Sarah resolve to investigate how the Daleks have re-emerged so early in Skaro's history by getting captured by a Dalek patrol. This is quickly done, but the Dalek which apprehends them is a Time War-style Bronze Dalek, and the Doctor spots a Dalek Time Ship in the distance, realising that future Daleks went back in time to help their own ancestors. However, the temporal crisis has grounded the Dalek Time Ship too, stranding the future Daleks in their own past. Sarah suggests that the Doctor offer to help repair the machine, with the secret intention of sabotaging it while learning more about the Daleks' plans.

Episode 3: Home Is Where The Hearts Are
K9 has now dropped in on the Twelfth Doctor and Bill Potts, whose TARDIS is stuck on Gallifrey. He advises the Doctor to use "Matrix Representation Icons" and "adaptive neogenesis molecules", which the Doctor knows better as Waypoint Cards and Henoch Matter, to upgrade the TARDIS's generator workers' efficiency. K9 also states that he detected a nearby cache of Kyfred Gems, which the Doctor decides to "borrow" so as to be able to easily buy any equipment they may need along the way. After they recover the Gems, K9 has a better idea: to use them as temporal "skipping stones" in the space-time continuum so as to "refocus temporal energy". They decide to do it through the Untempered Schism, with the Doctor giving Bill a protective shield to wear to prevent it "melting her brain". They walk through the Panopticon and out beyond the Citadel. When they get to their destination, however, the Doctor suddenly gets a premonition and sends a message through K9 to Sergeant Benton that he may soon encounter "Clara Oswald, a.k.a. Impossible Girl", and should do his best not to interfere with whatever she's doing. Benton readily agrees, but forgets to ask who she is and how he'll recognise her before K9 disappears again.

Episode 4: The Right Place At The Right Time
Now being chased through time by a Dalek, the Twelfth Doctor's newly-functional TARDIS makes an emergency landing in Nevada. After getting a message from River Song through K9, the Doctor walks out and is confronted with Clara Oswald wearing an American diner waitress's outfit. He seems to remember her, but is very confused to see her alive. She explains cryptically that she is "here to save you. Again, I think, one last time". The Doctor, with his memories, is very confused, as is what turns out to be another Clara Oswald — an earlier version, travelling with an earlier version of the Doctor. Their TARDIS, drained of power by an unknown source, also crashed here.

The Dalek chasing the older Twelfth Doctor soon catches up with them. However, it is confused by the presence of two Claras, one of whom is only debatably alive. The younger Clara takes advantage of its confusion to talk it into self-destructing, drawing on her experience as a Dalek to convince it in highly Dalek terms that its time-traveling has splintered its DNA and made it an impure failure ("Impure! Impure! And you've failed your mission! You have failed! You have failed!"). When the Doctor comments that the scene was somewhat disturbing, the older Clara wryly notes that she's done "much worse" since. K9 interrupts the conversation, calling out to the Doctor to say that he has identified the next Waypoint: Stonehenge.

Episode 5: All The Better To Sea You With
Martha Jones, travelling across the stations of the Osterhagen Project with Project Indigo, ends up pulled off-course to Atlantis. Realising that she's ended up in the wrong place, she activates Project Indigo again, thinking to herself "There's no place like home".

Moments later, the Fourth Doctor's TARDIS lands in the same place. He walks out with K9 Mark I, who detects "redisual energy from a vortex manipulator". Before he can tell him anything more, K9 malfunctions. The Doctor realises that the time crystal is to blame, and that they've become stuck in a time eddy.

Episode 6: The Pandorica Prologue
When K9 Mark IV checks in at the UNIT HQ laboratory, Benton asks him if he can take a message back to the Doctor, whichever one is most readily available: apparently, NATO anti-submarine equipment has been "acting up", and the Brig is worried that it's "the Sea Devils again". K9 uses his vortex manipulator circuit to transport himself to the location of the Twelfth Doctor: the Underhenge at Stonehenge, the "Pandorica Waypoint". Just as the Doctor is explaining the nature of the Pandorica to the immortal Clara, they are attacked by a pair of Cybermen guarding the Pandorica. Though unarmed and not even remembering what Cybermen are properly, the Doctor puts up an unflappable front.

Episode 7: In All The Towns In The World
Jo Grant enters the UNIT HQ laboratory looking for the Doctor, only for Benton to explain that the Third Doctor and the Brig have been gone for a little while, having gone off to "some fancy shindig in Geneva": the United Nations are giving the Doctor an award for salvaging the peace conference "last January".

Elsewhere in time, a version of the Tenth Doctor is visiting ancient Atlantis with Martha Jones when he detects the presence of a vortex manipulator in a nearby temple using the sonic screwdriver. They rush there, and the Doctor is already rattling off the appropriate Shadow Proclamation warnings when the "tomb-robber" greets him with a "Hello, sweetie": it's River Song, who describes herself as the Doctor's wife. She explains that she intended to arrive literal moments before the sinking of Atlantis and rescue a "priceless artefact" which she intends to sell to the Lux Library Foundation. She is thus mildly confused to see that Atlantis is showing no signs of sinking. However, without further ado, she slaps a memory worm on the Doctor to make him forget the encounter and thus preserve the timeline, then dashes off.

Episode 8: A Deep One
Inside Clara's TARDIS, Ashildr moodily asks Clara Oswald if her meeting herself is going to turn into a regular occurrence. Clara explains that it shouldn't, normally, but that, since her splinters are widespread throughout the Doctor's time stream, their best course of action is to avoid running into the Doctor. According to her, they need to find someplace the Doctor would never go — somewhere exceedingly boring. Ashildr knows just the place, and they set a course for the Minyan ship.

Elsewhere and elsewhen, Atlantis, still in a time eddy, is being explored by Martha Jones in the company of a representative from the earlier version of UNIT: none other than Doctor Liz Shaw. They are confronted with a Sea Devil, who explains that their local Sea Devil hibernation pod was activated by the Doctors' vortex energy-collection, and have set things in motion to send out a signal that will awaken the millions of other Sea Devils hibernating around the world. Liz and Martha try to convince the Sea Devil to delay the awakening so that a peace plan between the reptiles and humanity can be worked out; the Sea Devil seems amenable, and Martha calls the Doctor for help. The Doctor arrives in the form of the Thirteenth Doctor, who begins negotiating with the Sea Devil.

Episode 9: Forgotten But Not Gone
K9 brings Rose Tyler to the Panopticon to meet with Sarah Jane Smith. Sarah Jane is just beginning to explain that she and her Doctor are drawing vortex energy from Skaro when they get side-tracked talking about how many times they've each faced the Daleks. Agreeing that the Panopticon is a risky place to meet, even with perception filters, they decide to move to a safer location to continue the conversation.

At the UNIT HQ laboratory, Jo is talking with Benton about the effort to recharge all the TARDISes when K9 appears and alerts them to the presence of an alien life-form somewhere within the space-time Waypoint, i.e. UNIT HQ. With a bit more data, the three realise that one or more Cybermen have reassembled themselves out of the broken parts stored in the UNIT Vault following the attempted Cyberman invasion of Earth. One breaks through into the lab, and K9 seems to have disappeared, but when it tries to capture Jo to convert her, she hits it in the chest with her golden bracelet, sending gold flecks into its respiratory system which prove sufficient to kill it. K9 returns to explain that gold is deadly to the Cybermen, clarifying that he had to teleport off to deal with other alien threats escaping from the Vault.

Episode 10: My Friend's Enemy Is Also My Enemy
Waiting for the Twelfth Doctor in the Panopticon, Bill is surprised to see Nardole, who she didn't know had been on the ship. He explains that the Doctor has told him to help with the vortex energy collection, hence his leaving the ship.

Meanwhile, the Fourth Doctor has returned to the Minyan ship P7E with Leela. He explains what he has learned from his future selves: Daleks from the early days of the Last Great Time War will attempt to attack the Minyans before they make it to their new home, afraid that, after being saved by the Doctor, they would return to being allies of the Time Lords. Indeed, the Minyans detect a Dalek ship, but the Daleks board them instead of initiating a space battle. After coming aboard, two Daleks explain that they are here for the Minyan race bank which they want to "study" and then return "undamaged". The Doctor guesses the truth behind this un-Dalek-like behaviour before they can trick the Minyans: the Daleks intend to alter the genetic codes contained in the bank, so that the future generations of the Minyans will be ontologically loyal to the Daleks. While the Doctor distracts the Daleks, Leela manages to get behind them and startle them; they fire at her, not realising that she is now carrying a Minyan shield gun, which she uses to reflect their gunstick-fire back at them, destroying them. The Doctor congratulates her on her "excellent use of geometry".

Story notes

 * This story is one of few to explictly suggest that Clara Oswald was able to remember her splinters' lives: the main Clara states that her memories of crossing the Doctor's time stream are "a bit blurry now", but is still able to refer back to her experience as Oswin Oswald, using her inside knowledge of Dalek psychology to thwart another Dalek.
 * Episode 8, which features a Sea Devil, is entitled A Deep One. The Deep Ones are antediluvian, fish- or batrachian-like sea-dwelling humanoids from the works of H. P. Lovecraft. All-Consuming Fire previously implied that Lovecraft's Deep Ones and the Sea Devils were one and the same.
