White Rabbits
There’s a total of five white rabbits that can be found around the arena. Each one is on an object that represents a letter to spell out the phrase S LIES, which was originally found Monaco.
It was confirmed by Robert Runesson, the Executive Producer of THE FINALS, that the white rabbits are linked to lore:
ROBERT RUNESSON: the white rabbits in the CB1 (that evidently also will be in CB2) are actual THE FINALS lore…
Pipe Markings
At the beginning of Closed Beta 1, markings on some pipes in Data Center were found. Like with the white rabbits, it was confirmed by Robert Runesson that the pipe markings are linked to lore:
ROBERT RUNESSON: … these are linked to the lore and to the future… ._.
However, these markings were eventually removed. It is unknown when exactly they were removed, but it was sometime after Season 1.
