Neurospasm

Neurospasm is a first-person roguelike horde shooter. You fight hordes of fleshy enemies and bosses using weapons and active abilities, which power up as you get kills. Each run takes you through five procedurally generated layers with different styles, enemies and mechanics.

Items and weapons

You can collect and stack over 100 unique items. Items can alter your weapons and bullets or your stats, grant passive abilities, or spawn helpful buddies; stacking makes their effects more powerful. You can use up to six weapons at once.

Runs and progression

Random events can change how entire layers play. You earn money based on your performance and spend it between runs on permanent upgrades. Secrets hidden across the maps unlock modifiers that change how the game plays.

Endless mode

Endless mode remixes the base game. Your score is based on your kills, and you can compare it on a worldwide leaderboard.
