Arcade U-Boat Strike

Arcade U-Boat Strike is a single-player arcade game.

The player controls a U-boat, whose goal is to destroy as many ships as possible in a limited time period. The U-boat moves horizontally, and fires vertically, while an unending number of ships of various speed, size, and distance stream across the screen. Faster, further, and smaller ships are worth more points. Enemy ships fire at the player, and if they are hit, they lose time and 50 points. The player starts with 150 seconds, and gains an additional 50 second bonus if they reach 1,000 points. Each additional 500 points is worth a further time bonus.
