Bug Alliance is a top-down Action Roguelite where every level-up reshapes your build. Trigger Synergies, conquer 20-wave maps with boss finales, unlock a 13-chapter story on higher difficulties—then dive into Chaos Surge with endless bosses, curses, and risky rewards.

A brutal pixel-action RPG where bugs rise against the worm empire. Fight in 3 unique game modes, evolve through battles, and reclaim your world — forge your legend in Bug Alliance!
After the Earth faces the catastrophic meteor strike, everything changes once and for all. With the extinction of humanity, it leaves its place to a new mutated life. This "New World" is mainly ruled by two forms of living, Bugs, and Worms. Worms try to devour the nature to feed their greedy King - Glutton.
Bugs, on the other hand, under the command of their Queens, pledged to protect the nature and the whole living from hoggish worms at any cost. After losing the great battle, bugs and their queens are captured, tortured, and enslaved. Many years later, bugs create a secret alliance, called “Requiem Society”, with the mission to unite all of the brave and mighty Bug warriors across the continent and fight back for the Volucris and the Queens!
