EVENT TIMERS
Scheduled or triggered countdowns to future events — the raid arrives in three days, the ritual completes at midnight, the supply drop lands in ten minutes — displayed so players can plan against them.

XCOM 2's Avatar project clock drives the whole campaign's tension, Darkest Dungeon-likes and roguelike campaigns use doom clocks to prevent infinite grinding, and live-service games structure play sessions around timed events. Designers use visible timers to convert open-ended play into decisions under pressure: with a deadline, every activity has an opportunity cost, and 'what do I do next' becomes 'what can I afford to do first'. Timers also create anticipation arcs — dread before a raid timer, excitement before a reward event — that untimed sandboxes lack. Key decisions: whether timers are exact, fuzzy ('enemies approach in ~2 days'), or hidden until imminent, whether player action can delay or accelerate them, and how many run concurrently before planning collapses into anxiety. Pitfall: a global doom clock that outpaces the fun — if players feel punished for engaging with side content, the timer isn't creating tension, it's taxing exploration; generous or player-slowable clocks preserve pressure without the resentment.
