The day before the closed beta went live, content creators were able to post footage from an event. Creators mentioned the view from the top of the crane in Seoul and Rob commented “you can see a WR from there.... ._.” and “just something for you to follow..!”. These were the first clues that there was something to find in the closed beta playtest.
White Rabbit

On March 7th a white rabbit was found on the VEIN sign on the Seoul map by 9th.Grizzy, its best seen in spectator mode and its located on the outside of the building. Players can stand on top of the sign, and destroy the sign too.
On March 11th Rob posted “1 WR found in seoul 5 days… I was thinking 2.8 days per WR would be more than enough…”. As the beta was running for 14 days this meant there were 5 white rabbits to be found, he also confirmed this was on the Seoul map.
On March 12th Rob confirmed that the WR’s will stay in the game after the beta.
Trismegistus

On March 11th on the Seoul map, binary code was noticed on a screen in The Infirmary by Vogue. The binary translates in the format as column down, left to right and spells Trismegistus.
