Came also out for:
Sea Dragon is an arcade style side scrolling shooter. You pilot a submarine through treacherous underwater caves in an attempt to destroy a heavily guarded reactor. Mines, gun turrets, and a variety of enemies make the mission very difficult! The submarine is armed with missiles, torpedoes, and a ‘Big Kill’ weapon (this affects everything onscreen) to help in your mission. The air supply is limited, so when possible you will need to surface to replenish your air supply.
What I think:
Really hard game, but that makes it addictive.
