Bug Alliance
Steam
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.

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.
Play as a growing roster of bug warriors—each built around a distinct combat identity.
Each character supports multiple build paths—from raw damage and critical bursts to sustain, defense, and control—depending on how you upgrade.

Onslaught is the heart of Bug Alliance—a focused, replayable wave experience.

Bug Alliance’s campaign is structured as Prologue + 13 Chapters, delivered through 13 maps—and the story is earned through mastery.
Complete Extreme to unlock that map’s endless variant…

Chaos Surge is an endless mode where the game keeps raising the stakes.
The longer you survive, the more your build is tested—and the more legendary it becomes.
Every run is shaped by choices.
When you level up:
Upgrades can enhance:
Each item has a max level, so committing to one path means sacrificing another—making every run feel personal and strategic.

Push your gear to its peak and unlock Synergies—powerful transformations that change how your weapons and abilities behave.
With the number of combinations across upgrades, stats, tactical gear, and Synergies, every character supports thousands of viable build possibilities.

Bug Alliance rewards every run—win or lose.
Unlock the world behind the war.
