Quests¶

Scripted encounters with a fixed spawn timeline. The player clears all enemies to complete the quest.

Starting conditions¶

Weapon: defined per quest (Pistol unless noted).
Bonuses: enabled, with stage-specific suppression (see Bonuses — suppression rules).
Perks: enabled, manual selection on level-up.
Terrain: defined per quest.

Spawning¶

Each quest has a spawn table of timed entries. A timeline counter advances with game time, and entries fire when their trigger time is reached. Each entry can spawn one or more creatures in a formation with fixed spacing.

If no living creatures remain and the spawn table still has entries, the timeline keeps advancing. If the table has entries but no creatures have been active for over 3 seconds (and timeline > ~1700 ms), the next entry is force-triggered to prevent stalls.

Hardcore¶

Hardcore difficulty becomes available after completing all tier 1-4 quests on normal. It maintains a separate progression track: you replay quests from 1.1 with tougher spawns. Most multi-spawn entries get +8 extra creatures, one special entry class gets +2.

Completing all tier 1-4 quests on hardcore unlocks the Splitter Gun.

Completion¶

A quest is complete when both conditions are met:

Spawn table is empty.
No living creatures remain.

The completion transition takes about 2.5 seconds: feedback sound at ~0.8 s, music transition at ~2 s, result finalized at ~2.5 s.

Failure¶

If all players die before completion, the run is marked as failed. A record is still written for stats and score tables.

Scoring¶

Ranked by fastest completion time. Failed attempts are ranked behind completed ones. The record includes elapsed time, kills, shots fired/hit, and most used weapon.

Each quest unlocks a weapon or perk on first completion. Start weapon is Pistol unless noted otherwise.
