Underground – 6

Enter code 23 in the tape machine and pick up tape labelled “Vendome_Ba”. Go to the TV and watch the tape. Step back from the TV.

This achievement is part of the same ARG mentioned above. It involves trailer of “The Past Within” for Nintendo Switch and the game “The Past Within” itself. The trailer shows two codes 3Y1 and XZ2 which can be entered in The Past Within. The exact solution is described in the ARG document mentioned above. Basically Vendome Barroso is an anagram of Rose Vanderboom and that’s how we get “Vendome_Ba” (or “”Vendome_Barro” when the tape is in the TV).
