\*fINTRODUCTION\fR
.pp
Well, the federation is once again at war with the Klingon empire.
It is up to you,
as captain of the U.S.S. Enterprise,
to wipe out the invasion fleet and save the Federation.
.pp
For the purposes of the game
the galaxy is divided into 64 quadrants
on an eight by eight grid,
with quadrant 0,0 in the upper left hand corner.
Each quadrant is divided into 100 sectors
on a ten by ten grid.
Each sector contains one object
(e.g., the Enterprise, a Klingon, or a star).
.pp
Navigation is handled in degrees,
with zero being straight up
and ninety being to the right.
Distances are measured in quadrants.
One tenth quadrant is one sector.
.pp
The galaxy contains starbases,
at which you can dock to refuel,
repair damages, etc.
The galaxy also contains stars.
Stars usually have a knack for getting in your way,
but they can be triggered into going nova
by shooting a photon torpedo at one,
thereby (hopefully) destroying any adjacent Klingons.
This is not a good practice however,
because you are penalized for destroying stars.
Also, a star will sometimes go supernova,
which obliterates an entire quadrant.
You must never stop in a supernova quadrant,
although you may "jump over" one.
.pp
Some starsystems
have inhabited planets.
Klingons can attack inhabited planets
and enslave the populace,
which they then put to work building more Klingon battle cruisers.
\".bp
.ce
\*fSTARTING UP THE GAME\fR
.pp
To request the game, issue the command
.sp
.ti +15
.ft B
/usr/games/trek
.ft
.sp
from the shell.
If a filename is supplied,
a log of the game is written onto that file.
(Otherwise, no
file is written.)
If the
``\fB\-a\fP'' flag is stated before the filename,
the log of the game is appended to the file.
.pp
The game will ask you what length game
you would like.
Valid responses are "short", "medium", and "long".
You may also type "restart",
which restarts a previously saved game.
Ideally,
the length of the game does not affect the difficulty,
but currently the shorter games tend to be harder than the longer ones.
.pp
You will then be prompted for the skill,
to which you must respond
"novice", "fair", "good", "expert",
"commodore", or "impossible".
You should start out with a novice
and work up,
but if you really want to see
how fast you can be slaughtered,
start out with an impossible game.
.pp
In general,
throughout the game,
if you forget what is appropriate
the game will tell you what it expects
if you just type in
a question mark.
\".bp
.ce
\*fISSUING COMMANDS\fR
.pp
If the game expects you to enter a command,
.hc ^
it will say ^"Command:\ "
and wait for your response.
Most commands can be abbreviated.
.pp
At almost any time you can type more than one thing on a line.
For example,
to move straight up one quadrant,
you can type
.ti +12
move 0 1
.br
or you could just type
.ti +12
move
.br
and the game would prompt you with
.ti +12
Course:
.br
to which you could type
.ti +12
0 1
.br
The "1" is the distance,
which could be put on still another line.
Also, the "move" command
could have been abbreviated
"mov", "mo", or just "m".
.pp
If you are partway through a command
and you change your mind,
you can usually type "-1"
to cancel the command.
.pp
Klingons generally cannot hit you
if you don't consume anything
(e.g., time or energy),
so some commands are considered "free".
As soon as you consume anything though -- POW!

.bl "Short Range Scan"
Mnemonic: srscan
Shortest Abbreviation: s
Full Commands: srscan
	srscan yes/no
Consumes: nothing
.FF
.pp
The short range scan
gives you a picture
of the quadrant you are in,
and (if you say "yes")
a status report
which tells you
a whole bunch
of interesting stuff.
You can get a status report alone
by using the
.ul
status
command.
An example follows:

The name of the starsystem is listed underneath
the short range scan.
The word "distressed", if present,
means that the starsystem
is under attack.
.pp
Short range scans are absolutely free.
They use no time, no energy,
and they don't give the Klingons
another chance to hit you.
.bl "Status Report"
Mnemonic: status
Shortest Abbreviation: st
Consumes: nothing
.FF
.pp
This command gives you information
about the current status
of the game and your ship, as follows:
.in +8
.de qq
.sp
.ti -4
..
.qq
Stardate -- The current stardate.
.qq
Condition -- as follows:
.in +4
.nf
RED -- in battle
YELLOW -- low on energy
GREEN -- normal state
DOCKED -- docked at starbase
CLOAKED -- the cloaking device is activated
.fi
.in -4
.qq
Position -- Your current quadrant and sector.
.qq
Warp Factor -- The speed you will move at
when you move under warp power
(with the
.ul
move
command).
.qq
Total Energy -- Your energy reserves.
If they drop to zero,
you die.
Energy regenerates,
but the higher the skill of the game,
the slower it regenerates.
.qq
Torpedoes -- How many photon torpedoes you have left.
.qq
Shields -- Whether your shields are up or down,
and how effective they are if up
(what percentage of a hit they will absorb).
.qq
Klingons Left -- Guess.
.qq
Time Left -- How long the Federation can hold out
if you sit on your fat ass and do nothing.
If you kill Klingons quickly,
this number goes up,
otherwise,
it goes down.
If it hits zero,
the Federation is conquered.
.qq
Life Support -- If "active", everything is fine.
If "damaged", your reserves tell you
how long you have
to repair your life support
or get to a starbase
before you starve, suffocate,
or something equally unpleasant.
.qq
Current Crew -- The number of crew members
left.
This figures does not include officers.
.qq
Brig Space -- The space left in your brig
for Klingon captives.
.qq
Klingon Power -- The number of units
needed to kill a Klingon.
Remember, as Klingons fire at you
they use up their own energy,
so you probably need somewhat less
than this.
.qq
Skill, Length -- The skill and length
of the game you are playing.

The three digit numbers
tell the number of objects
in the quadrants.
The units digit tells the number of stars,
the tens digit the number of starbases,
and the hundreds digit is the number of Klingons.
"*" indicates the negative energy barrier
at the edge of the galaxy,
which you cannot enter.
"///" means that that is a supernova quadrant
and must not be entered.
.bl "Damage Report"

Shortest Abbreviation: da

A damage report tells you what devices are damaged
and how long it will take to repair them.
Repairs proceed faster
