CD Projekt RED added to the remaster The Witcher 3 is a rather strange easter egg related to Cyberpunk 2077. You can find her in Velen.
There are three towers with switches next to the Ruined Bastion location. When you activate them, a portal will appear on one of the hills – if you enter it, Geralt will be in the bastion. If you go to the basement where immortal spirits live, you can find a mark on the wall Cyberpunk 2077.

Fans have already translated the characters on the tag and received the code “FF 06 B5”. It can be seen and Cyberpunk 2077 – He is depicted in one of the statues.

Phantoms do not yet know what to do with this label, what the code means and how to kill the ghosts. Some believe the secret is related to Ciri’s journey to the world Cyberpunk 2077, but no one has confirmed that yet.
CD Projekt RED previously responded to the poor optimization of the remaster. The company also began distributing unique armor for The witcher 3
