Swarm is a modifier in the game HOURS. When used it increases the number of enemies in one stage.
Description[]
Upon enabling Swarm in the main menu, every stage you enter when playing will spawn 10 enemies instead of the standard 5, and 3 of them can spawn at any given time instead of 2.
Swarm stacks with the Multiplayer modifier. When both are enabled, you will fight all 30 enemies in-game, 6 at a time in a single stage.
Swarm has no effect on Bosses, and does not change the format of the stage Light Beneath Closed Eyes.
Beating the game with Swarm enabled unlocks the tempo 
Cell.
Trivia[]
- Hands of Time used to be required in order to activate Swarm, but as of the 1/11/2022 Rework update, it is now free to use.
