About Dalton's Field Manual: Data Provenance, Methodology & AI Disclosure
Direct Answer: Dalton's Field Manual is an independent completionist tracker and technical troubleshooting reference for Terrible Lizards (Steam App ID 2920220). Every internal achievement key, unlock percentage, and patch workaround on this site is derived from primary Steam Store/Community JSON captures and official WDR Studios developer logs—never scraped or spun from secondary wiki farms.
Editorial Angle: Because 14 of the 15 Steam achievements in Terrible Lizards are hidden in the store UI and launch-week players needed immediate clarity on Chapter 2's 24th note and Level 3 framerate stutters, we built a verifiable, local-first web utility backed by raw telemetry snapshots.

2. Who Built This & How AI Was Used
Who: Dalton's Field Manual is maintained by an independent game-telemetry engineering team focused on fast, zero-bloat completionist tools for newly launched PC/console titles.
How & AI Disclosure: We use automated Python scripts to query public Steam Web APIs and SSR achievement schemas, then use AI-assisted code generation to structure interactive client-side calculators, OpenAPI specifications, and Markdown mirrors. Every number, achievement key, and patch note is strictly bound to captured JSON evidence; unknown or unconfirmed details are explicitly labeled rather than guessed.
