Save the Earth I: Chapter I

You are someone called John. He has just joined to an underground international organization called Earth Defense Organisation.

EDO found some very imperialistic aliens some time ago, and it seems that Earth is in crossfire between two different races (one friendly, one wants to conquer earth).

EDO has planted some spies to the imperialist alien ships and has gained information and even some new technology. Doweu (imperialist alien empire) is beginning to occupy the Earth (we have some very valuable raw materials). Doweu has bases in Mars, Moon and underwater, and yes, you guessed right, you must stop them.

Your very first mission is release our scientist which is held captive in Sub-base, but there is defenses between base and surface. You and your small one-manned sub can get past the mines, but you must destroy the mines, not only sneak through.

You have some torpedoes to do the job. When you're inside, there should be a small guard group and scientist somewhere. When the EDO is the owner of the place, you must get back to our transporter where you'll be teleported to orbital space station.
