Pytheas and the Simulation

Mooncrash opens with Peter outside the lunar base. KASMA’s assignments send you back into the simulation. Start with Andrius, take the first available escape pod and unlock the rest of the team. Changing characters within a run preserves opened doors, dropped equipment and already used escape routes.

Check power, tram status, available pods and corruption each run. Security workstations track people and pods. Use Delay_Loop.Time before corruption rises if you need time to prepare a safer route.

The companion Operator can hand gear to the next character in the same run. Give it spare parts, medicine and Neuromods you will no longer need before escaping.

Unlock All Five Characters

Andrius Alekna is available at the start. Escape once as Andrius to unlock engineer Joan Winslow. Joan can repair equipment for other characters in the same run.

Find Riley Yu’s Psychoscope upstairs in Pytheas Labs to unlock the Director. Track Vijay Bhatia at a security workstation and search his body to unlock the Security Officer. Finish Vijay’s story objective to unlock Claire Whitten, who can open terminals for the rest of the team.

Escape With All Five Characters in One Run

Unlock all five characters and practice the individual routes first. One workable team order: Joan repairs the portal and uses the Mass Driver. Riley escapes by emulating her consciousness. Claire hacks the portal controls and uses it. Vijay flies the shuttle. Andrius takes the escape pod.

Adjust the order for power and reachable areas. Riley needs her own route. Joan and Claire must prepare the portal in the same run. Set aside spare parts before Joan leaves and keep a navigation chip for Andrius.

Once the routes are complete, finish the individual memory objectives and outstanding KASMA assignments. Return to the satellite story and follow Basilisk’s final message.

The security workstation shows pod status.

Show solution

  1. Step 1

    Check pod status at a security workstation and mark a working pod.

    Later launches need a navigation chip. Fabricate it from the early plan, buy it in your loadout or recover one from a broken pod.

  3. Step 3

    Install the chip in the working pod and launch.

Shuttle – Pilot 1 and Launch

Crew Annex · Shuttle Station

Angela Wagner’s piloting connectome unlocks the ability.

How do I escape through the Mimic Portal?Mooncrash · Pytheas simulation

Joan repairs the portal controls. Claire hacks the terminal and can then escape through the portal.

  1. Plan both runs in the same simulation and take five Spare Parts as Joan. Have the Repair level required by your current corruption level.
  2. Take Joan to the portal in the Pytheas Labs and repair the control panel. Use a different escape route for Joan.
  3. Switch to Claire, hack Chao Wei’s computer at the required level and stabilize the portal. Then go through it as Claire.
