# Every command is actually parsed: in SysAdmin Crisis, tab completion and man pages both work > An offline night-shift simulation solved with a gamified Unix command set; one game engine runs the web and mobile versions at once. - What it does today: Has the player resolve seven incident types on a night shift through twenty-nine commands in a gamified Unix syntax (real flags, tab completion and `man` included); the web (PWA) and mobile (iOS/Android) versions share the same game engine.

The shift is built on seven incident types (starting with a DDoS attack and running through six more scenarios); the tutorial introduces two of them — a memory leak and a DDoS — at a slowed pace, using the same commands. ## One engine, two platforms The web (a Next.js-based PWA) and mobile (Expo) versions share the same game engine; on mobile the terminal screen is not a web page embedded in a WebView; it is drawn with native components. The ten-night campaign mode, with its rising load and reputation-to-budget loop, runs on that same shared engine; endless mode and its difficulty options are built on top of the same core. At the end of a shift the run is summed up with a letter grade (S/A/B/C) and a local top-ten list is kept; an unfinished run also stays local, exportable and importable, in a versioned save format. ## Development discipline is tied to the code chain Some things are not left to code review alone: on every push, dependency audit, lint, type-check, the test suite, coverage, the mobile test suite and the web build all run automatically in CI. The end-to-end suite and the accessibility audit run outside CI, in the developer's own environment — the accessibility audit is kept free of serious or critical findings. ## Zero data collection is enforced in code No accounts, no analytics, no ads — the game makes no network request while playing, aside from the initial page load and the web version's service worker update. That is not a privacy paragraph; it is a constraint tied to the build chain: `fetch`/`XMLHttpRequest` use inside the game packages is blocked by lint rules, and analytics or ad clients leaking into a dependency are caught by a separate dependency-audit script. The record sits here as halted: it was prepared for release as v1.0.0 and is playable today at sysadmincrisis.com, but no further development is happening on it.
