About this game
WASD to move, Space to dash!
In this Survivors-like action game, you’re not the hero — you’re the boss.
Run for your life as waves of little heroes try to take you down. Collect gold, equip weapons, and grab power-ups to become an unstoppable force. Got duplicates? Combine two like weapons to craft even more powerful versions and discover synergies that fuel your survival.
Enjoy the immersive music and satisfying sounds as you battle through growing hordes. This is an early playtest — and for now, all playable characters are unlocked, so you can experiment with a variety of builds and find your favorites.
There are a limited number of waves right now, encouraging shorter sessions and more build variety. As we continue developing alongside our community, we’d love your feedback! Let us know what you like, what you don’t, and what you want to see added next.
