Warning Forever is a boss battle shoot'em up. When you beat the boss spaceship, a warning will sound for the next approaching boss spaceship. Warnings go on forever because you only fight bosses. From English readme.txt Start the game, and suddenly there's a boss. Kill the boss, and there comes the next boss, and the next, and the next. Slowly but surely, the game gets insane.
