A player is on a mission to destroy the ultimate weapon of their enemy. It involves travelling through a set of precarious tunnels in their high-tech hover-craft. The tunnels are filled with enemy vehicles, choppers and sentry guns which the player has to take out or avoid. To make life even worse, a lot of sections require the player to clear them in a given time limit. The only good thing is that the player will be able to upgrade their weaponry often.
