Every process needs authority. Authorisation Engine is an offline incremental strategy game about building a system that authorises everything. You begin at a merchant payment desk, manually approving transactions and tuning fees against demand. From there, the operation grows into API capacity, automated authorisers, compute infrastructure, treasury strategy, tournament simulations, quantum ledger tools, and finally synthetic jurisdictions where agents map coverage and close unresolved claims. Build the engine Authorise transactions manually, then automate the desk. Balance fee pressure, demand, live TPS, and API capacity. Buy projects that reshape production, compute, mandates, and network behavior. Expand from a local payment desk into clearing houses and synthetic economies. Use treasury, tournaments, quantum tools, and agent allocation to push the system further. Play offline with local saves, export/import support, and no ads or in-game purchases on Steam. A dense operational interface The game is built around dark terminal panels, green authorisation systems, live route pulses, resource pressure, and a holographic world view. It is designed for desktop play first, with Steam Deck readability as a core target. The Steam version The Steam release is the complete paid desktop game.
