Poizone

Navigate twisting mazes in Poizone, a cooperative maze and collection game released by Eterna in 1991. Players control two penguins—Zozo among them—tasked with clearing toxic blocks from each level while searching for magic diamonds. Success requires careful planning, as players must work together to maneuver through the increasingly complex environments and avoid hazards along the way. Gameplay centers on strategically eliminating a significant portion of these hazardous blocks to progress. The simple controls – an 8-way joystick and single button – belie the challenge of coordinating actions with a second player to overcome obstacles and collect all the diamonds scattered within each maze. Poizone features distinctive graphics and music, demonstrating Eterna's technical capabilities at the time; its ARM processor powers a surprisingly engaging experience for two players seeking a puzzle-based arcade challenge.
