Polybius Invaders

Polybius Invaders is a single-player arcade shoot ’em up in which you fight General Goo’s forces across 25 stages of alien invaders. Destroy the waves sent by the evil General, collect weapon pick-ups and face four bosses before the final showdown with General Goo.

Optional effects

You can manually enable Infra-Sound and Subliminal Messages during gameplay; both appear on the GUI when active and can be turned off at any time. The game describes Infra-Sound as a sound undetectable by the human ear that induces fear. These features are optional.

Arcade influences

The game pays homage to early-1980s arcade games, including Space Invaders and Duck Hunt, and draws on the urban myth of “Polybius.” It combines a challenging retro-style design with modern aesthetics.
