ARG/Whiprock Prison Cell

Whiprock Prison Cell is a post-release ARG set piece added to INFRA in 10th Anniversary update on the January 16, 2026.

Setup

After completing INFRA above 50% to receive the Winds of Change ending, a bottle of Stollandia Vodka is found on a shelf inside Mark's home office.

Drinking the vodka will transport Mark to a prison cell on Whiprock Island, which itself is an excerpt from yet-unreleased infra_dlc1_m2_prison map module from the upcoming Whiprock DLC.

Mark can hang around for a maximum of 5 minutes or interact with the prison cell door to exit, either way results in him waking up on a sofa in the living room.

Stollandia Vodka bottle

That brand of bottle was introduced for the first time in Obenseuer game with the Overhaul update, and was ported back to INFRA with textures remade in higher quality with additional information.

On the bottle's label a barcode is found, marked with string RED-E.1, decoding the barcode itself also returns the RED-E.1 string. Format of this code matches the ARG/The Tunnel Of Water Trees book puzzle, suggesting the first word in the E.1 S.9 H.8 C.2 sequence might be Red.

On the other side of the label the following text is found, it does not seem to have any significance to the ARG or its puzzles besides being humorous:

THE BEST VODKA YOU CAN GET
FROM THE STOLLAND. DRINK
THIS SHIT INSTEAD OF THAT
DAMN SLOP CALLED OSMO
OLUT, JUST DON'T DRINK TOO
MUCH OF THIS SHIT I MEAN
IF YOU WANT TO KEEP BUYING
THIS STUFF, YOU HAVE TO BE
READY TO DIE!
STOLLAND\TS

Whiprock Prison Cell

The prison cell has its ceiling and walls covered in various scribblings.

Trivia

• This is the first time the full country name was acknowledged in INFRA, after it was prior revealed by the developer and later properly established in Obenseuer game first.
• Along this set piece, all sorts of other Whiprock DLC assets were released as well, that seems to contain content related to the ARG, although it is not officially used in any capacity yet.
