Theseus Protocol is a deck building strategy roguelike developed for PC. Players take on the role of Prometheus in a dystopian setting called Mark City, where they build and refine decks of cards while using an array of weapons to navigate hostile environments and confront enemies.
Gameplay
The core loop centers on turn-based combat that incorporates positioning as a key tactical element. Players move their character to avoid attacks and can maneuver enemies into collisions with one another for additional damage or disruption. Cards form the foundation of offense and defense, with any unused cards at the end of a turn converted into ammunition for equipped weapons. This system encourages careful management of resources across each encounter.
Deck building progresses across multiple runs as players acquire new cards, upgrades, and equipment. Weapons receive enhancements that alter their performance, adding layers of customization to combat approaches. Three distinct playable characters provide different combat styles and separate narrative perspectives, allowing for varied strategies and story threads depending on the chosen protagonist.
Game Modes
The primary experience unfolds through roguelike runs that feature branching paths across the city. Each attempt reveals more of the fractured narrative while building upon previous progress with retained cards and upgrades. Successive playthroughs encourage experimentation with different deck compositions and character choices.
Deep Dive Mode serves as an additional option that lets players adjust certain rules before starting a run. This mode supports customized experiences and tracks performance through scoring systems, with achievements tied to high scores or specific deck restrictions such as using only attack cards.
Narrative and World
The story of Mark City unfolds gradually through repeated runs rather than in a linear sequence. Players uncover details about elitist conspiracies, gang conflicts, and the history of its inhabitants by exploring different routes and completing encounters. The setting emphasizes a fractured, dystopian atmosphere where each decision in combat and navigation contributes to revealing background information on the world and its characters.
Is It Worth Playing?
Theseus Protocol appeals most to players who enjoy strategic deck builders with roguelike elements and turn-based combat that rewards positioning and resource management. The game launched in early access in early 2023 before its full release later that year, and subsequent updates introduced features such as Deep Dive Mode, a compendium for reviewing cards and equipment, and weapon upgrades.
Reception stands at mixed levels, with 66 percent positive ratings from several hundred reviews on the primary distribution platform. Positive feedback often highlights the tactical depth of battles and the integration of cards with weaponry, while some criticism focuses on narrative presentation. Those seeking a focused single-player experience with replayability through deck experimentation and character variety may find value in the title, particularly if they prefer deliberate strategy over faster-paced action.
