FRAGMENT: PROTOCOL is a deterministic 3D roguelite dungeon crawler that runs entirely in the browser on PlayCanvas and WebGL. Descend a procedurally generated tower, draft protocol cards that rewrite your ruleset each run, and push your score as far as the anomaly floor allows.
Every session is driven by a published daily seed. The same seed and the same input tape always produce an identical run, which means the server can re-simulate a submitted run from scratch and verify the final score rather than trusting the client.
Rooms are laid out with a binary space partition, then decorated with a wave function collapse pass that constrains tile adjacency on every edge, so geometry stays coherent, connected, and reachable without hand-authored maps.
Cards are drawn from rarity tiers that shift the rules of the run itself: common modifiers, rare synergies, and prime-tier protocol rewrites that change how the floor behaves.
