Spoilers ahead: for the puzzle and the movies/games
This post assumes you've already solved the puzzle. It reveals all categories and their connections, and discusses plot details, endings, and spoilers for featured movies/games throughout.
Silent Service came from Sid Meier before Civilization turned his surname into a genre label. The game puts a Pacific submarine under your command and assumes sonar, torpedoes, and patience count as a relaxing evening.
Games: Metroid: Zero Mission · Metroid: Samus Returns · Metroid II: Return of Samus · Metroid: Other M
Metroid II gives Samus an extermination order on SR388. Samus Returns rebuilds that mission for Nintendo 3DS, adding melee counters and free aiming to a Game Boy hunt that originally worked with far fewer buttons.
Zero Mission revisits her first trip to Zebes. Other M sends her into the Bottle Ship, where a distress call leads to another Metroid weapons program. Samus keeps accepting assignments from people who have learned nothing.
Games: Bad North · Townscaper · Kathy Rain · Kingdom Eighties
Raw Fury's four games barely share a genre. Bad North is tactical island defense. Townscaper is a building toy with no goals beyond making a place look pleasing enough to resent real municipal planning.
Kathy Rain uses Adventure Game Studio for a 1990s mystery, while Kingdom Eighties turns the Kingdom formula into a summer-camp fight. The publisher label is the bridge, not a house style.
Games: AquaNox · Silent Service · 688(I) Hunter/Killer · Diluvion
AquaNox makes undersea combat fast and arcade-like. 688(I) Hunter/Killer leans into modern submarine simulation, where identifying a contact can matter more than firing first.
Diluvion adds crew management and exploration to a flooded world. The connection works because the submarine is not a level or a vehicle pickup. It is the player's body, workplace, weapon, and increasingly damp home.
Games: Thexder · Robotech: Battlecry · Future Cop: LAPD · Gun Metal
Thexder flips between robot and jet. Future Cop: LAPD changes its X1-Alpha between a walking combat machine and a hovering pursuit vehicle. Gun Metal follows the same logic with a fighter jet form.
Robotech: Battlecry supplies three Veritech modes: Battloid, Guardian, and Fighter. That middle form is the clue that this group is about direct transformation, not climbing into a separate car and pretending it counts.
The submarine row asks players to live inside the machine. The tricky row asks the machine to become the commute. The same date's CineLinkr puzzle has equally unstable identities, only with spies and department-store mannequins.
