Spoiler: this is a collision route
The GIGA patch officially says that a surprise was added where determined players had already managed to reach. The route itself is not presented as a normal door interaction: two current Steam guides demonstrate using collision behavior to enter Jenny's house from the garage.
Because the method depends on collision, a later patch can change how forgiving the doorframe is. Save in a separate slot before trying it, and use the built-in Stuck option if the character cannot leave normally.
How to enter Jenny's house
- Bring at least one beer can, then go inside the garage where cards are cleaned and fragments are glued.
- Face the closed interior door and move tightly against the right-hand doorframe—the side touching the wall.
- Look down toward the bottom of the frame and keep pressing into that corner.
- Drink the beer while holding that position. The can collision can push the player through the doorframe into the lower floor of the house.
- Once inside, use the stairs and continue upstairs to see the surprise added by the GIGA patch.
If the doorframe method does not work
- Re-center on the right edge of the door rather than the middle of the door panel.
- Keep the camera angled down and stand flush against both the frame and adjacent wall.
- Try the beer action again from a slightly different distance; the route depends on the can touching the character and nearby collision.
- Do not edit coordinates or save files for this route. The reviewed guides demonstrate it with normal in-game objects.
How to get back out
The same collision can sometimes be repeated from inside, but the safer documented exit is the menu recovery control. Press Escape and choose the Stuck option to return to a normal playable position.
The guides establish an upstairs surprise, not a permanent inventory reward. Do not plan 100% completion around receiving a card, figurine, or achievement from the room unless the game itself awards one in your current build.
Where is the KOTAMON secret location?
It is inside Jenny's house beside the garage. Current community routes enter through the garage's right-hand interior doorframe using a beer-can collision.
Do I need cheats or coordinate editing?
No. The reviewed screenshot and video guides demonstrate a route using normal movement and a beer can.
How do I leave the secret room?
Open the pause menu and use the Stuck recovery option if you cannot reverse the collision route.
