Progress in recoverable steps
The Steam listing identifies The Thing That Happened as a single-player game. A strong progression plan is therefore one that works at your own pace: establish the immediate objective, prepare for it, and bank the lesson before moving deeper.
Learn from pressure
If a route, encounter, or craft choice fails, use that result to revise the next attempt. The confirmed systems—crafting, weapons, attachments, and close-combat skill trees—give you several ways to adjust without needing an invented “meta.”
Confirm changeable information
The official Steam page is the authority for availability and product information. Recheck it when an update could affect your plan.
