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