To the Basement. Before

You are one of the few flying drones that have not been affected by the virus.
Your mission is quiet, but crucial: to penetrate the depths of the infected bunker and find what remains hidden in its sections. Something that will later play a key role in the fate of the entire complex.
With each level, the corridors become more dangerous: unstable mechanisms, security system traps, hidden blocks that are easy to break - all of this is hidden in the darkness. But the drone has a special vision that allows it to see things that are usually invisible, and this is sometimes the only thing that saves you from death.
Along the way, you'll encounter epic bosses, such as malfunctioning security machines and distorted structures that have been transformed into unpredictable creatures by the virus.
The game is a side-scrolling arcade game where flying, maneuvering, destroying obstacles, avoiding traps, and battling bosses all come together in a dark journey through the infected depths.
