- "I'm not trying to persuade you out of this, Rip. I'd just like it if you didn't die."
- ―Ricardo (from Alien: Isolation)
Deputy Ricardo was a member of the Colonial Marshal Bureau on Sevastopol Station. When a lone Xenomorph was unleashed on the station by the crew of the Anesidora in 2137, Ricardo and his fellow officers struggled to keep order. He was encountered by Amanda Ripley when she arrived on Sevastopol to recover the USCSS Nostromo's flight recorder, which had also been brought there by the Anesidora.
Ricardo was subdued by a Facehugger while he helped Ripley to arrange an escape from the station, and she was forced to leave him to his fate.
Torrens crew arrival
After the crew of the Torrens arrived on the station on December 11, Waits and Ricardo found Christopher Samuels and Nina Taylor. During an argument between Waits and Samuels, Amanda arrived with medical supplies for Taylor. Waits explained to Ripley that the Alien was brought on board the station by Henry Marlow, the captain of the Anesidora, the ship that found the Nostromo's flight recorder.
The group went to the Colonial Marshal Bureau. Ripley asked for Ricardo to which Waits replied with that he was "prepping our next move". Ripley spoke with Marlow, who was being kept in a cell by Waits because of his refusal to follow quarantine procedures.
After Ripley finished talking to Marlow, she joined Waits' plan to contain the Alien by attempting to trap it in the Lorenz SysTech Spire. Amanda later met up with Ricardo and the two kept in contact with each other over Ripley's headset. As she finished locking down all the escape routes and initiating the emergency lockdown, Ricardo was unable to get the exit door open, ultimately sealing Amanda inside the area with the Drone. Ricardo eventually resorted to overriding the lockdown to open the exit and save Ripley, at the expense of allowing the Xenomorph to escape.
With "Plan B" failed, Waits suggested that Ripley takes the elevator to a remote location of Sevastopol, the Gemini Exoplanet Solutions lab, to lure the Drone there in a second attempt to trap it. However, once the Alien was contained, Waits ejected the module from the station with Ripley still inside. Amanda was eventually able find an EVA suit and eject herself from the module to return back to Sevastopol, while the Alien was left behind in the jettisoned module as it fell into KG348.
As Ripley made her way back to the Bureau, Ricardo contacted her, surprised that she survived and apologized for his botched efforts with the lockdown. She unenthusiastically accepted the apology.
Working Joe rampage
Once the was Alien disposed of, the situation aboard the station appeared back under control, but the station's androids abruptly began hunting down and killing the station's remaining human survivors. Eventually, a group of Joes had reached the Bureau and began attacking Waits and the Bureau's inhabitants. When she later returned to the Bureau, she discovered Waits' corpse, along with the other survivors she had previously encountered that were killed by the Joes. The only member to survive was a distraught Ricardo, who had hid from the androids.
Ripley goes off looking for Samuels, who went to consult with APOLLO. Ricardo, though still clearly in shock, stayed behind and kept in contact with her over comms, with Ripley needing "eyes and ears". In order to put a stop to the slaughter, Samuels interfaces with APOLLO. Despite Ripley's attempts to save him, Samuels is killed by APOLLO's defensive countermeasures, but not before he opens a path for Ripley to APOLLO's control core. Ricardo later guides her to it, though the two eventually lose contact with each other.
With Ripley's efforts in disengaging the androids failed, APOLLO redirects her to the station's reactor core, in which she encountered a hive. Ricardo was against her exploring any deeper into the nest and urged Ripley to leave. She later destroyed the nest by initiating a reactor purge, though multiple Xenomorphs were able to escape. The purge resulted in multiple systems being reset on the station. Ricardo sought this to be an opportunity to contact the Torrens and headed for Seegson Communications, whilst Ripley went to the San Cristobal Medical Facility to pursue Marlow, who was holding Taylor hostage in the Anesidora. The two later lost contact a second time.
Marlow had initiated an overload in the Anesidora's reactor, intending to blow up the ship as well as the station. Amanda was forced to flee the ship and return to Sevastopol, with Taylor and Marlow dying in the explosion.
After Ripley had aligned the station's transmitter dishes using the Torrens coordinates, she told Ricardo that they were leaving. Ricardo expressed his gratitude but was cut of mid-sentence and Amanda lost contact with him. Amanda later approached the office he was using and discovered he had been attacked and subdued by a Facehugger, forcing Amanda to abandon him. He was later killed either when the Chestburster inside him erupted or when the station burned up in KG-348's atmosphere, though the latter being almost guaranteed due to the time frame.
Personality and traits
Unlike his superior Waits or Marlow, Ricardo had a amicable disposition to Amanda, neither betraying her or having ulterior motives. He tried to help her the best he could over the radio but suffered from mild survivors guilt after Waits and other survivors are murdered by the androids. Amanda herself seemed to like Ricardo and was saddened when she discovered he had been subdued by a Facehugger.
Behind the scenes
Originally, Alien: Isolation writer Will Porter planned to have Ricardo's Facehugging take place far earlier in the story, while Ripley was cut off from him inside APOLLO. He would subsequently recover with little memory or understanding of what happened (as with Kane in Alien). Despite growing fears that something was wrong, he would keep the situation secret from Ripley until the point of the Chestburster emerging, which was to occur after the communications dish realignment. However, upon reflection, the team realized that the gestation period should be considerably longer — the process took around 24 hours in Alien. Thus, Ricardo's fate was changed so that he simply falls victim to a Facehugger later in the game. In an interview with AvPGalaxy, Porter later accepted the change, stating, "That came with its own added elements of horror, when he presumably regains consciousness off-screen, so we gained something there."
- Ricardo is a playable character in the Alien: Isolation DLC The Trigger.
- Amanda may be indirectly responsible for Ricardo's fate, as after destroying the original nest, the new one lacked hosts and so facehuggers began roaming the station to find some with one eventually finding Ricardo. This is also the point where players would start encountering them on the station as well.
- As revealed in The Trigger, Ricardo is indirectly responsible for kick-starting the events of Ripley's journey throughout Sevastopol, as the explosion that had severed the EVA line, separating Ripley from Taylor and Samuels was the result of Ricardo setting explosives in an area in an attempt to kill the Xenomorph.
