A submarine game written in BASIC. You start at the left of the screen and must navigate till the dock to the right. The submarine is just a pixel controlled by the keyboard. In the upper half of the screen some magnitudes are shown, like longitude, latitude, depth and navigation speed.
During the travel you'll randomly come across some enemy ship, so the screen changes to alert mode, you'll see then your periscope, and use it to move and shoot torpedoes. You must shoot quickly as if the submarine is closer than 300 m the ship will throw depth charges and you must avoid them.
After avoiding all these dangerous boats, at reaching the naval base it's the final challenge, controlling the submarine to enter the base fighting against the strong sea current.
A nice game consisting of different, original 'mini-games' that make you spent a nice gaming time.
