Rivage The K9 System

K9 is the reason Rivage can ask you to loop without turning station A.R.E.S. into homework. It is a persistent implant in Miranda Vigneau, not a tablet you might drop, and not a pause-menu codex you forget to open. On May 1, 2467, the first thing the station tells you is that the canine system has been reset and that most of the crew is missing. Your job is to fill that empty log faster than the power bar empties.

Official copy calls it the K9 System: Miranda logs discoveries and retains certain puzzle solutions so later loops spend energy on new rooms. Player-facing, it is four tools glued together: a discovery log, a screenshot camera, a solution bank, and a flashlight. If you treat it as optional UI, you will retype Stardust in the dark. If you treat it as the only inventory that survives Time Trickster, the demo’s hour makes sense.

Turn it on in the first room

Do not wait for a second loop to “get serious.” The birthday recovery, the book title, and the first locker glyph all happen in quarters. Photograph them. Store the working password. The getting started guide puts this at the top of the first-session plan because every later machine assumes you still have those strings.

K9 is always with Miranda. There is no bench to craft it and no shop to upgrade it. Rivage is single-player only and has no microtransactions; the implant is a design layer, not a progression tree. What grows is the quality of what you stored.

What K9 keeps

• Discoveries. Codes, names, service unlocks such as pod-bay access, and notes that the station considers solved knowledge.
• Screenshots. Whiteboards, barcodes, plant labels, locker interiors, reader levels, and anything you will not remember when the flashlight is the only light.
• Puzzle solutions. Once a cube, card, or panel is banked, you should not have to reconstruct it from muscle memory after a reset.
• Flashlight. When intensity drops, the station asks you to activate the K9 light. That is how you finish seating a pharmacy cell or read a storage room that only opened because the grid died.

What K9 does not keep: the object in your hand, a battery left in a hallway, a key you did not use on the kitchen box, chairs you shoved, food you moved. Those belong to the loop. The walkthrough calls this out on the pharmacy route because people lose a whole morning carrying cell number three when they should have seated cell number two.

Screenshot discipline

A.R.E.S. is a cluttered Unreal Engine 5.7.4 interior. Labels are small. Barcodes are worse. The broken keycard puzzle in the demo path punishes players who enter digits from a fading mental image while the interface clicks under a drag. Take a still of each segment. Take a still of the finished code. Take a still of the reader that accepted it, including its level, so you do not spend the next loop waving a level-two card at a level-four lobby lock.

Screenshot even when you think K9 already “knows.” The log stores what the game flags as a discovery. Your camera stores what your eyes noticed: a glyph that matches a cabin locker, a plant name that might be a password later, a to-do line about Aman’s box. The crew roster will not hover over the prop. You will.

If storage is on your mind, be picky rather than spraying. A still of a blank bulkhead is a tax on you during the next review. A still of Johnny’s battery note is a route.

Solutions as efficiency, not skip buttons

Banking a puzzle does not teleport you across the station. It means you do not re-solve the astro lab cube to prove you are allowed in the kitchen. Power is still spent walking. Power is still spent booting a menu. The gift is attention: loop three can be a battery run with no cube detour.

Use that gift with the loop planner. If K9 already holds pharmacy access, do not reopen that menu unless you are confirming a service. If K9 already holds the barcode, go straight to the reader that needed it. The implant is how Rivage stays a mystery instead of a typing test.

Flashlight and the blackout

Low light is not a fail state. It is a lighting pass with extra rules. Activate the K9 flashlight when asked. Look for doors that were electronic a minute ago and are manual now. Look for storage that evacuation logic unlocked. Time Trickster is usually in that newly honest dark. You can still interact with local-power machines. You cannot pretend the main bus will reboot if you stand still.

The flashlight does not replace planning. If you have no seated cells and no new screenshot, you are in a pretty blackout. Reset. Fill K9 on the next morning.

Story, not a pet

The canine naming is a character beat. Miranda is not walking a dog through the station. She is living with an implant that talks like a ship system and a companion at once. Story trailers lean on that voice. Logs from Miranda and the missing crew sit beside K9 entries because the implant is how she refuses to forget them when the day rewinds.

Do not expect K9 to solve moral questions about the anomaly. It will not tell you where Dahia went. It will tell you the code you already earned so you can keep looking.

Habits that survive into the full game

The campaign launches on September 22, 2026 with more rooms, which makes a sloppy log more expensive, not less. Practice now:

1. After every solved machine, confirm it is in K9 before you walk away.
2. After every new glyph, take a still even if you cannot use it yet.
3. Before Time Trickster, glance at what you are holding. Seat it or drop it on purpose.
4. After a reset, open K9 before you open a door. Spend power on the frontier.

Controls for opening the implant and toggling the light live in the in-game remap list; see controls rather than memorizing a guessed key. The guides hub links every system page. K9 is the one you should reread if a loop taught you nothing. The station already reset. Your notes do not have to.
