The 1666 Amsterdam prologue is a short introduction, approximately 30 minutes long, introducing players to the core mechanics of the upcoming project from Patrice Désilets, creator of Assassin’s Creed and Prince of Persia: The Sands of Time. The demo features virtually no combat—the developers are emphasizing exploration, mysticism, magic, and storytelling.
This guide will tell you how to complete the prologue of 1666 Amsterdam, which cat to choose, where to find the necessary books in the library, and how to complete the introductory chapter.
Walkthrough of the prologue of 1666 Amsterdam
After starting a new game, create a save slot. The prologue begins with the cinematic sequence familiar from Summer Game Fest 2026. Control will soon be yours.
The forest and the first lessons of magic
Move forward along the only path. You’ll soon discover the body of a dead animal. The game calls such objects Life Echoes .
Press the button that activates Noah’s abilities, then hold down the interaction key to collect Lux energy .
The resulting energy can be used to activate magical objects:
- focus on the goal;
- aim at the objects with floating red leaves;
- enchant an object;
- light it.
After this, all the torches along the road will light up at the same time, and the path will open further.
Sacred tree
At the end of the path, you’ll reach a large gathering of people near a withered, leafless tree. This is the Sacred Tree . A cutscene with the game’s title will appear here.
Once the cutscene ends, collect Lux’s energy again from the nearby Life Echo.
Now you need to activate the brazier on the left. This will automatically light all the other braziers around the tree.
When the appropriate clue appears, use the revive ability and then examine the tree itself. Analysis will reveal more about the mysterious cats associated with this ritual.
Which cat should you choose in 1666 Amsterdam?
The next important choice is choosing your Bateratze. The game offers nine different cats:
- The Spirit is the keeper of the secrets of the other world;
- The Hermit is a truth-seeking sage;
- The Dreamer is a free wanderer of other currents;
- The Wildling is the embodiment of nature;
- The Guardian is a protector and symbol of perseverance;
- The Alchemist is a researcher of the elements and transformations;
- The Child is a curious and spontaneous explorer;
- The Page is a student who strives to understand the world;
- The Knight is the personification of courage and honor.
Which cat should I choose? Currently, this choice has no impact on gameplay. In the prologue, all options are identical, differing only in description.
Bateratze will likely become the protagonist’s constant companion and play a more important role in the full version of the game.
Library: Where to find the books you need
After another cutscene, the action shifts to the present day. You now control Clio, Aaron Long-Smith’s daughter.
Go up the stairs and talk to Professor Lucas.
After the conversation, go downstairs and approach the table near the fireplace. Talk to the professor again.
He will ask you to find a book related to ancient writings.
Where can I find the first book?
The required section of the library is located to the left of the professor’s desk.
Look for Section VI , which is devoted to ancient writing systems and languages.
Analyze the Roman numeral, then examine the bookshelf and interact with the book. Take the clue you found and return to the professor.
Where can I find the second note?
After the conversation, go upstairs again.
Now you are interested in section XIV , located directly above the professor’s desk.
Examine the Rembrandt bust and take the hidden note.
Give it to the professor to continue the story.
Aaron’s Memories
The next scene takes players to the year 2000.
You will control Aaron, who, together with Agnes, returns to the Amsterdam hotel.
The route here is completely linear. Follow the signs from the floating text until you reach the elevator.
Where can I find all the relics in the room?
Once inside the hotel room, collect three items:
- Dry leaves are lying on the shelf on the left;
- Four candles – located in a wooden chest opposite the entrance;
- Tapestry – lies in the bag on the sofa on the right.
After collecting all the relics, a new cutscene will begin.
Playing as a cat
Now control will pass to your Bateratze.
Follow the linear path, jumping between objects. Soon you’ll pass through the red gate and find yourself back at the Sacred Tree.
Time seems to have stood still here.
Examine the tree and the figure of a girl in a red hood.
You will learn that her name is Noa , and you will also hear her nickname – The Collector .
How to complete the prologue of 1666 Amsterdam
Go around the Sacred Tree from the opposite side.
Glowing symbols will be hovering above one of the branches. Jump onto the branch and move to the right.
Go down and interact with the bluish ghostly trace.
After this, the introductory chapter will end.
What happens after the prologue?
The prologue of 1666 Amsterdam introduces players to key characters, demonstrates the basics of using Lux’s magic, and hints at the important role of Bateratze cats in the future plot.
The full game is scheduled to launch in Early Access sometime in 2026. Judging by the demo, the project combines exploration, mysticism, elements of witchcraft, and storytelling with a strong emphasis on the atmosphere that made the early Assassin’s Creed games so beloved.
