Power Station - Military Base B423 (Basement)

The information has been known for several months, a disused American base, closed in 1991, is located at the 21 rue du Sentier.
A new way to access (illegally) the B-423 military complex has been found! This time the exploration takes place in the 1st basement of the base, a staircase prohibited to the public will take you to this abandoned area.
POWERSTATION seems accessible to exploration. Reinforced concrete walls, drainage pipes, electrical room, someone will guide you to the entrance... but can you get out of there?

Gaetan_S18's opinion: A very friendly welcome, and a very immersive atmosphere in the room! The head-on exploration works really well for the first few minutes. The storyline is cleverly constructed. We all had a great time!

The opinion ofAmélie B. : Great immersion and gripping storylines! The PowerStationl is pretty complicated, so get ready! :p

The opinion of Ludovic G. : Although the disused military base is a bit technical, it serves its purpose perfectly, providing a good level of thinking and logic with a touch of stress: a must-do!
