This free minigame gives you an early taste of the upcoming action-roguelite Eclipse Breaker. Step into a Boss Rush mode designed for quick, high-intensity runs that showcase the game’s parry-driven combat and active-time battle flow. Perfect for anyone who wants to see how far they can push their skills in a single sitting. Every run throws you against a lineup of bosses with escalating patterns and punishing attacks. Learn their tells, master your dodges and parries, and unleash devastating counters. Runs take 15–20 minutes , making it easy to jump in for “just one more try.” This Boss Rush mode will also be included in the main Eclipse Breaker game at launch. Play it now for free, then come back during Steam Next Fest for the full demo with roguelite progression, companion allies, loads of equipment and upgrades, and more bosses to conquer. Developer's Note Hi everyone, I’m Jorge Rodriguez, the developer of Eclipse Breaker. This project is my tribute to the roguelites and PlayStation-era RPGs that defined my love of games, blending fast-paced, timing-driven battles with the sense of mystery and danger I grew up chasing. I've had a lot of fun developing this game, and it’s been a joy to bring that idea to life. The minigame you’re about to play is just one game mode available in the full release, and your feedback is incredibly valuable as we keep building toward the launch later this year. Whether you’re here for the strategic combat, the nostalgia, or to test your skills against impossible odds, thank you for giving Eclipse Breaker a try. Now go face the challenge, and see how long you can last!
