  • Players who prefer simple turn-based combat may hit a wall when they must manage cards, ammunition, and battlefield positioning together.

Our take on Theseus Protocol

Players may bounce off when combat requires several systems at once: building a deck, preserving leftover cards for ammunition, changing position, and manipulating enemy collisions. The repeated-run structure can also test patience for anyone expecting the full story in one straightforward campaign.

What is Theseus Protocol?

Theseus Protocol combines deck building, turn-based combat, and roguelike progression in a dystopian science-fiction setting.

Players take the role of Prometheus and travel through branching routes in Mark City while uncovering its divided history, conspiracies, and conflicts. Battles use cards, weapons, and position changes: movement can avoid attacks or make enemies collide. Cards remaining after combat actions can serve as ammunition for Prometheus's weapons. Successive runs develop the deck and reveal more of the narrative. Three playable characters offer different combat approaches and separate story threads, while repeated playthroughs expose additional parts of Mark City's history.
