About Theseus Protocol
Theseus Protocol is a deck-building strategy roguelike set in a dystopian world. You play as Prometheus, travelling across different lands, fighting relentless foes and uncovering the secrets of Mark City as you try to change humanity’s fate.
Mark City’s story
Mark City is divided by elitist conspiracies and gang-driven turmoil. Its fragmented narrative unfolds along branching paths across successive playthroughs, revealing the city’s history and that of its inhabitants. Each step contributes to uncovering the truth.
Turn-based battles
Combat combines cards, weapons and tactical positioning. You can move to dodge incoming attacks or make enemies crash into one another, and use leftover cards as ammunition for Prometheus’ weapons. Build your deck across successive runs, choosing cards that support your strategy.
Playable characters
The game has three playable characters, each with a distinct combat style and narrative thread. карточ
