About Bug Alliance

ENTER THE SWARM
Bug Alliance is a top-down Action Roguelite where every run is a new experiment—and every level-up is a real decision. Fight through escalating waves, shape your build through upgrades and Synergies, and earn your progress across a story-driven campaign that rewards mastery.
THE STORY
Earth didn’t just fall—it turned desperate. As forests vanished and survival collapsed, humans engineered bugs to last longer… then escalated into cruelty: breeding, reshaping, and enslaving entire species as food, tools, and weapons.
The swarms mutated, fought back, and forced humanity from the planet—yet not all of them died. A remnant fled, watching from afar. In the silence that followed, three Queens rose to unite the surface and form Volucris—while far beneath, the leftovers of human experiments continued to evolve into something far worse.
