Find all 12 hidden Among Us crewmates found throughout the episode:
Master Bounty Hunter: after using Convert, Henry's squad enters the warehouse. The Red crewmate is next to a cabinet.
Cleaned 'em Out:
When Henry jumps off the Toppat Train as it arrives at the launch site, the Yellow crewmate can be seen on a crate.
When Henry is in the rocket and uses Leafmöde, the Blue crewmate is on a crate behind him.
Toppat 4 Life, if Ellias Bahtchin orders Phantom to nuke the military camp, the Green crewmate is located next to Phantom.
Toppat Civil Warfare, when executing the Midnight Surprise plan, the Pink crewmate is seen in the ventilation duct with the electrical defense.
Capital Gains, when Henry and Ellie wonder how to empty the money cart of the wrecked Toppat Train, the Orange crewmate is seen among the gold.
Revenged: At the start of the story, when Henry wakes up on board Dr. Vinschpinsilstien's ship, the Black crewmate is next to his bed.
Free Man: When Henry uses the Remote and gets ejected into space, the White crewmate can be seen floating in space.
Jewel Baron: The Purple crewmate is in the vault of the Toppat Orbital Station. He can only be clicked just after Henry teleports inside after choosing Teleporter.
Triple Threat: If Henry and Ellie use Parasols to land on the control tower, the Brown crewmate can be seen inside the tower (far right).
Valiant Hero: The Cyan crewmate is in the luxury escape pod during the final choice screen.
A Tan crewmate can be found in the Trash Ball. Tan is not needed for the achievement, and clicking on it will create a fist that punches it away. This references the development of Among Us, where Tan was considered but ultimately rejected. Interestingly, Tan would later be re-added to Among Us in 2021.
Stickmin Space Resort: When Icepick and Sal Malone are arguing about switching hats, the Lime crewmate is in the open truck to the right.
