42 ** PHOTON TORPEDO CONTROL
44 ** Either one or three photon torpedoes are fired. If three
45 ** are fired, it is called a "burst" and you also specify
48 ** Torpedoes are never 100% accurate. There is always a random
49 ** cludge factor in their course which is increased if you have
50 ** your shields up. Hence, you will find that they are more
51 ** accurate at close range. However, they have the advantage that
52 ** at long range they don't lose any of their power as phasers
53 ** do, i.e., a hit is a hit is a hit, by any other name.
55 ** When the course spreads too much, you get a misfire, and the
56 ** course is randomized even more. You also have the chance that
57 ** the misfire damages your torpedo tubes.
