The player views the landscape from behind a hovering craft and flies over fields, water, and other terrain. The main objective is to stop the virus before it spreads across the environment and produces increasingly dangerous organisms.

Spraying infected ground slows or removes the threat, but flight is sensitive and collisions can destroy the craft. Enemy forms and environmental hazards increase the pressure as a level continues. Progress depends on controlling the outbreak and surviving each stage rather than simply reaching a destination.

Keep the craft moving in broad, controlled passes rather than making abrupt turns. Treat infected areas early, because allowing the virus to spread creates more dangerous targets and reduces safe space.

Stay aware of altitude and terrain while spraying. Avoid chasing every threat immediately; preserving control and returning to a manageable part of the landscape is often safer than flying aggressively into crowded areas.
