Duo Bad Brothers

Two zombie brothers must get out of a dangerous laboratory by working as a team. Their different abilities make the adventure a cooperative puzzle: the larger brother can smash wooden barriers and handle doors, while the smaller brother can slip through narrow openings.

The goal is to gather three stars and arrive at the exit together. Success depends on choosing the right brother for each obstacle and keeping both characters involved as you cross the laboratory. The two-player design gives every movement a useful purpose, especially when a path is blocked for one brother but open to the other.

Use WASD for one character and the arrow keys for the other, or choose mobile touch controls.

Guide both brothers through the laboratory and collect all three stars before attempting the exit.

Use the big brother to break wooden walls, then send the little brother through spaces that are too small for him.

A double jump is available when a normal jump cannot reach the needed path.
