About This Game

Venice, 1500. Four witnesses, four objects on a long table.

Anna Notaras is the daughter of Byzantium's last great duke. She left before the end and has spent fifty years ransoming the City's survivors. Now she is writing down what they saw. Each witness who sits at her table leaves something on it: a notched tally-stick, a clay water bowl cracked and riveted back together, a ledger page whose seal has never been broken, a tassel. Their accounts do not always agree. She writes them down anyway.

1453: Fall of Constantinople is a choice-driven, illustrated historical novel about the fifty-three days of the siege, April 6 to May 29, told from both sides of the walls.

The testimonies

The Janissary. Born Greek, taken as a boy, now besieging the city his grandmother prayed toward. Anna's note on him: "He prays in two languages and lies in neither. Believe him about the wind."

The Baker's Daughter. Keeps the ovens, the queues and the rumours of the Petrion quarter going while the bread runs out.

The Engineer. A foreign specialist in the war under the walls: tunnels, water bowls floated to hear the digging, a burning siege tower.

The Noble. Carries the emperor's secret census, sits in on the surrender embassies, and weighs the Church's gold for the mint.

All four live by the same fixed calendar, and how it ends is known. The choices are about who each of them is in the last days of May.

Where the stories cross

A mercy shown in one testimony becomes a sixth ending in another. A berth bought, or refused, at court becomes the boat a girl might board on the last morning. A finished testimony visibly changes scenes and endings in the ones you read after it.

What the sources say

After every chapter the game shows where the scene comes from: an eyewitness diary, a later chronicle, a legend written down centuries afterwards, or that no source speaks to it. The sources codex flags every major event as attested, reported, legend or disputed.

On the table

• Four routes with five or six endings each, twenty-two in all, inside Anna's frame story.
  
• Painted-realism scenes of the siege, with slow ambient motion behind the text.
  
• A score that moves between mehter rhythm and Byzantine chant as the story crosses the walls.
  
• Ottoman and Byzantine lives written with the same care. No side's ending is presented as the true one.

Images and music are AI-assisted with human editorial control; text and code are human–AI co-written.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

1453 contains pre-generated AI content. Nothing is generated while the game runs. The in-game illustrations (the scene paintings and the parchment reading surfaces) were created with generative image tools from curated reference images, under human art direction, and reviewed for historical accuracy. Their slow on-screen motion is animated in code, not generated video. The music, the ambient soundscapes and the sound effects were generated with AI audio tools, then selected, edited and looped under the author's direction. The one exception is the interface click, a human recording released under CC0. The narrative text is human–AI co-written and human-edited under the author's direction, and the game design is the author's. On the store page, the capsule artwork was made the same way as the in-game illustrations, as were the library artwork and the store page background; the trailer's cinematic shots animate the game's own illustrations with AI image-to-video tools, and the trailer's music was generated with an AI music tool.

Mature Content Description

The developers describe the content like this:

1453: Fall of Constantinople is a historical novel about a siege, written for adult readers and delivered in prose and illustration. It depicts fifteenth-century warfare and its consequences: bombardment and mining under the walls, wounds and death in combat, and the killing of captives — including prisoners executed within sight of both armies. It follows the civilian cost of a siege as closely as the military one: hunger as the bread runs out, families divided by the walls, and the captivity and ransoming of survivors after the city falls. Religious conflict between Christian and Muslim characters runs through the whole story, and both sides are written as fully human; no side's account is presented as the true one. Adult characters drink wine. The game contains no sexual content and no nudity. Violence is carried by the writing rather than by graphic imagery.
