All Hands, General Quarters!

You man a deck gun on-board  a US naval vessel in the Pacific ocean.
Suddenly, from the east, a squadron of Zeros approach, intent on sinking your fleet.
Man your guns, mind your ammunition and shoot down as many enemy aircraft as you can.

Several difficulty levels are included.

Additional ammunition can be gained by kill streaks, or shooting down enemy supply aircraft.

Online leaderboard tracks the highest scores and the most kills.
