What is the secret of Kallipolis in The Callisto Protocol?
You can only get the gold trophy “The Common Ground” in The Callisto Protocol if you do this Mystery of Callipolis solves. To do this, you need to find and listen to two audio logs – the game calls them data or implant bios. But they aren’t just lying around, they’re placed in two secret rooms.
Caution: The Callisto Protocol is a linear action-adventure. If you cross a certain section, you cannot return. As described in our The Callisto Protocol tips guide, you should save manually on a regular basis. There is no chapter selection after the end of the game. You can only collect missed items if you start the game over again.
Mystery of Kallipolis: Find the first data bio
The first find is the Duncan Cole – Secret Room 1 data bio. You can find it in Chapter 3 – Aftermath while searching for the medical area. Do you have reached the laundry, go through the door on the left and follow the corridor straight until you see a locked door on the right. To open it, remove the switch box cover and cut the power supply with the knife.
On the other side, crawl right through the red-lit shaft. Keep right and you’ll reach a vault covered in bloodstains. Follow the corridor and jump at the end into the hole in the ground. Run to the left and you will reach the secret room. The boardroom is hung with red banners. The data bio is on the glass desk at the end of the room.
Mystery of Kallipolis: Find Second Data-Bio
For the second data bio “Yannick Sage – Secret Room 2” you have to advance to Chapter 6 – Below. Jacob is separated from his companion and tries to to reach the transportation center. In the depths of the station, you will encounter new zombie-like beings who can neither hear nor see.
Sneak through the corridors until you reach the location of the automatic pistol. We have described the way to you in our weapon guide to The Callisto Protocol. Follow the path until you reach a ladder in front of a large fan. Climb up and you’ll see on the right Sign that reads “Electric Reactor”. Instead of taking the path to the reactor, go left into the gap in the rock face.
The path leads directly to the secret room. On the way you have to eliminate a few zombies. The data bio is back on the table at the end of the room. Listen to the audio track and the Commonality trophy is yours.
