3.TH BATTLESHIPS 6 "Aug 23, 1989"
4.SH NAME
5bs \- battleships game
6.SH SYNOPSIS
7bs [ -b | -s ] [ -c ]
8.SH DESCRIPTION
9This program allows you to play the familiar Battleships game against the
10computer on a 10x10 board. The interface is visual and largely
11self-explanatory; you place your ships and pick your shots by moving the
12cursor around the `sea' with the rogue/hack motion keys hjklyubn.
13.PP
14Note that when selecting a ship to place, you must type the capital letter
15(these are, after all, capital ships). During ship placement, the `r' command
16may be used to ignore the current position and randomly place your currently
17selected ship. The `R' command will place all remaining ships randomly. The ^L
18command (form feed, ASCII 12) will force a screen redraw).
19.PP
20The command-line arguments control game modes.
21
22.nf
23 -b selects a `blitz' variant
24 -s selects a `salvo' variant
25 -c permits ships to be placed adjacently
26.fi
27
28The `blitz' variant allows a side to shoot for as long as it continues to
29score hits.
30.PP
31The `salvo' game allows a player one shot per turn for each of his/her ships
32still afloat. This puts a premium scoring hits early and knocking out some
33ships and also makes much harder the situation where you face a superior force
34with only your PT-boat.
35.PP
36Normally, ships must be separated by at least one square of open water. The
37-c option disables this check and allows them to close-pack.
38.PP
39The algorithm the computer uses once it has found a ship to sink is provably
40optimal. The dispersion criterion for the random-fire algorithm may not be.
41.SH AUTHORS
42Originally written by one Bruce Holloway in 1986. Salvo mode added by Chuck A.
