I found it as part of the ZCN repository: https://github.com/jamesots/zcn

The C source has been modified for VT100 compatibility and some minor changes have been made by me (Anna Christina Naß acn@acn.wtf.

bs.com is the compiled binary.

See the *.txt files for more information.

Modes

• -b selects a "blitz" variant
• -s selects a "salvo" variant
• -c permits ships to be placed adjacently

The "blitz" variant allows a side to shoot for as long as it continues to score hits.

The "salvo" game allows a player one shot per turn for each of his/her ships still afloat. This puts a premium scoring hits early and knocking out some ships and also makes much harder the situation where you face a superior force with only your PT-boat.

Keys

To position your ships: move the cursor to a spot, then type the first letter of a ship (using CAPITAL letters) type to select it, then type a direction ([hjkl] or [4862]), indicating how the ship should be pointed. You may also type a ship letter followed by r' to position it randomly, or type R' to place all remaining ships randomly.

Navigation and aiming keys:

k / 8	move up	n / 3	move down+right
r	place this ship randomly	R	place all ships randomly
^L	screen redraw	Q	quit game

Compiling

HiTech C has been used to compile it, but it needs a lot of free memory (TPA).

For compiling, I used the command c bs.c in CP/M.
