Chrome & Covenant uses a three-tier mission structure that scales from a single scene to a full campaign. Every tier feeds into the next.
Blip
A single scene or job. One session. A delivery, a heist, a conversation that changes everything. Blips are self-contained — they resolve in one sitting. The Milk Run is a Blip.
Echo
A five-layer “pressure chamber” spanning 3–8 sessions. Each layer escalates the tension. An Echo is the signature C&C adventure structure — designed so every decision ripples forward. The Echo Protocol (the free jump start) is a complete Echo.
Reverb
A campaign arc built from multiple Echoes. Reverbs are the long game — faction allegiances shift, characters change, and consequences from early sessions echo into the finale.
Book Expansion: The Chrome Gospel includes complete Echo construction tools, layer templates, faction interaction frameworks, and campaign management guidance.
