Tunnel B1

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

The game takes place on various levels with different objectives. For example, you might need to escort a key character to a certain point or defend it from enemy attacks. You can also collect power-ups and items to help you in your quest.
