About

Operation Drizzle! is a boss-rush action game that supports online co-op for up to 4 players. Dive into enemy territory solo or with friends and fight through a chain of back-to-back boss battles.
Combat is built around learning patterns. Study each boss’s tells, dodge with precise timing and invincibility frames, create openings, and focus your firepower to turn the tide.
Game modes: Single-player / Online co-op (1–4 players)
Playable characters: 3 available now, with 2 more planned
Boss roster: 20+ bosses, each with distinct attack patterns
Typical run time: ~5 minutes / ~30 minutes
We plan to expand the game with additional content over time, including:
More playable characters
Upgrade / item systems (details to be announced)
Pattern-driven boss fights with readable telegraphs
Fast, skill-focused action built around dodging and timing

Reina
A well-rounded all-rounder — reliably balances damage and survivability in any situation.

Grace
A hit-and-run speedster — rapid strikes that never miss an opening.

Hanna
A heavy front-line brawler — instead of dodging, she stands her ground and parries incoming attacks in head-on fights.
