43 ** Klingon Attack Routine
45 ** This routine performs the Klingon attack provided that
46 ** (1) Something happened this move (i.e., not free), and
47 ** (2) You are not cloaked. Note that if you issue the
48 ** cloak command, you are not considered cloaked until you
51 ** Klingons are permitted to move both before and after the
52 ** attack. They will tend to move toward you before the
53 ** attack and away from you after the attack.
55 ** Under certain conditions you can get a critical hit. This
56 ** sort of hit damages devices. The probability that a given
57 ** device is damaged depends on the device. Well protected
58 ** devices (such as the computer, which is in the core of the
59 ** ship and has considerable redundancy) almost never get
60 ** damaged, whereas devices which are exposed (such as the
61 ** warp engines) or which are particularly delicate (such as
62 ** the transporter) have a much higher probability of being
65 ** The actual amount of damage (i.e., how long it takes to fix
66 ** it) depends on the amount of the hit and the "damfac[]"
67 ** entry for the particular device.
69 ** Casualties can also occur.
