GLOBAL THREATS
A campaign-scale antagonist force that grows on its own schedule — an advancing doom project, spreading corruption, escalating invasion tiers — pressuring the player's strategic layer everywhere at once.

XCOM 2's Avatar Project is the archetype (a visible progress bar the player raids to delay), They Are Billions' final horde and Against the Storm's forest hostility escalate by design, and grand strategy end-game crises (Stellaris) reset the board's power math late in a campaign. Designers deploy global threats to solve strategy's pacing problem: without external pressure, optimal play is infinite turtling, and campaigns dissolve into administration. A clock that punishes passivity forces prioritization — you cannot answer every alert, so triage becomes the core skill — and gives the whole campaign a narrative spine with rising stakes. Key decisions: whether the threat is delayable, only survivable, or defeatable; how visible its progress is (XCOM's bar creates dread precisely because it's always on screen); and how it scales to player success — rubber-banding keeps pressure alive but can feel punitive. Pitfall: a doom clock tuned so tight it forbids the game's own content — if engaging with side systems means losing to the timer, players optimize into joyless critical paths and the strategy layer's richness goes unplayed.
