U-7008

Take the control over a little submarine and try to sail as far as you can!

But things aren't as easy as they can sound. The submarine is quite old and its control could appear difficult for rookies. The in-game tutorial is highly recommended.

Your submarine also needs fresh air and energy, you must take care of it during your sail.

Oh, and by the way you should avoid mines, boats, toxic barrels and it would be nice not to crash the seabed.

Good luck, sailor!
