Battle At Sea: WWIII

Fun submarine game. Destroy enemy subs and aircraft. You are DCON-7. You must save the earth. The year is 2033. Resources have run out. Global warming has taken its toll. Rebels have launched an invasion of the US. And, if that weren't bad enough—aliens have invaded and are threatening us all at our weakest time in history.

Attack with air and naval weaponry. Each level gets progressively more difficult. Bosses are at every five levels. Beat the game, and re-play 25 levels on TURBO mode—faster but just as fun.
