|---|
| 5 | battle [ -b | -s ] [ -c ] | 
|---|
| 6 | .SH DESCRIPTION | 
|---|
| 7 | This program allows you to play the familiar Battleships game against the | 
|---|
| 8 | computer on a 10x10 board. The interface is visual and largely | 
|---|
| 9 | self-explanatory; you place your ships and pick your shots by moving the | 
|---|
| 10 | cursor around the `sea' with the rogue/hack motion keys hjklyubn. | 
|---|
| 11 | .PP | 
|---|
| 12 | Note that when selecting a ship to place, you must type the capital letter | 
|---|
| 13 | (these are, after all, capital ships). During ship placement, the `r' command | 
|---|
| 14 | may be used to ignore the current position and randomly place your currently | 
|---|
| 15 | selected ship. The `R' command will place all remaining ships randomly. The ^L | 
|---|
| 16 | command (form feed, ASCII 12) will force a screen redraw). | 
|---|
| 17 | .PP | 
|---|
| 18 | The command-line arguments control game modes. |

|---|
| 20 | .nf | 
|---|
| 21 | -b selects a `blitz' variant | 
|---|
| 22 | -s selects a `salvo' variant | 
|---|
| 23 | -c permits ships to be placed adjacently | 
|---|
| 24 | .fi | 
|---|
| 25 |  | 
|---|
| 26 | The `blitz' variant allows a side to shoot for as long as it continues to | 
|---|
| 27 | score hits. | 
|---|
| 28 | .PP | 
|---|
| 29 | The `salvo' game allows a player one shot per turn for each of his/her ships | 
|---|
| 30 | still afloat.  This puts a premium scoring hits early and knocking out some | 
|---|
| 31 | ships and also makes much harder the situation where you face a superior force | 
|---|
| 32 | with only your PT-boat. | 
|---|
| 33 | .PP | 
|---|
| 34 | Normally, ships must be separated by at least one square of open water. The | 
|---|
| 35 | -c option disables this check and allows them to close-pack. | 
|---|
| 36 | .PP | 
|---|
| 37 | The algorithm the computer uses once it has found a ship to sink is provably | 
|---|
| 38 | optimal. The dispersion criterion for the random-fire algorithm may not be. | 
|---|
| 39 | .SH AUTHORS | 
|---|
| 40 | Originally written by one Bruce Holloway in 1986. Salvo mode added by Chuck A. |
