Spyship S.O.S

After an extremely successful spying mission, you are on your way out of the enemy base through the huge access tunnel with information vital to your side when you are discovered by an enemy patrol. Immediately you send an S.O.S. signal to your home base - but can you survive until help arrives? As time progresses the aliens become increasingly worried that you will escape with their secrets, so they bring out their hyper-weapons to stop you. A successful mission will end you your rescue by a fleet from your home planet.
