Warp is a real-time space war game.  This means that the enemies will keep
playing even when you sit still.  Another peculiarity is that things which
blow up can damage other things around them.  Universes above a critical
density may chain react.

The game starts at difficulty 1, and gets more difficult with each
succeeding wave, up to difficulty 99.  You're not likely to get that far.
(Invoking warp with a -b switch causes the difficulty to increase more
slowly, but games count only a tenth as much.)  The game starts with
5 Enterprises and 3 Bases, and you get more for surviving long enough.
The game is over when you run out of Enterprises and Bases.

The object of the game is to get as many points as possible.  This is done
by destroying as many enemies as possible.  This is not a trivial task.
Each wave starts with one Enterprise and one Base, and continues until
either both the Enterprise and Base are destroyed, or all the enemies
(including any homing torpedoes) are destroyed.  It is possible to abort a
wave, but you will be penalized for it.  The game may be saved between waves.

A -x switch causes any saved game to be ignored, and causes the new game
not to be saveable.  Hence it is possible to run test games without
invalidating a currently saved game.

The game is played in a 23 x 40 double wrap-around universe.  Everybody
(both you and the enemies) gets the chance to move once every second,
unless a -l (low-speed) switch was given or you are under 2400 baud, in
which case it's every two seconds.  The following symbols are displayed:

The following keys control the DIRECTION of your various actions:

	h or 4          left
	j or 2          down
	k or 8          up
	l or 6          right
	b or 1          down and left
	n or 3          down and right
	y or 7          up and left
	u or 9          up and right

(You will note that the letters are the same as other visual games, and the
numbers are for use with a keypad.)  By themselves, these keys move either
the Enterprise or the Base, whichever is the current vessel.  When shifted,
they fire photon torpedoes in the specified direction from the current
vessel.  When used with either the CTRL key or the FUNCT key, phasers
(turbo-lasers for the Base) are fired in the specified direction.  (CTRL
won't work with numbers, and FUNCT probably doesn't exist on non-TVI
terminals.)  When preceded by an 'a', an attractor beam is fired in the
specified direction, and when preceded by an 'r', a repulsor beam is fired.

These keys have special functions:

	del or %        fire photon torpedoes in every (reasonable) direction
	s               stop all friendly torpedoes
	S or 0          stop the Enterprise when in warp mode
	d               destruct all friendly torpedoes (quite useful)
	D               destruct the current vessel (commit suicide)
	i/w             switch to Enterprise and put into impulse/warp mode
	c/v             switch to Enterprise and put into cloaking/visible mode
	p		switch to Base (not very mnemonic, but 'b' is taken)
	o               switch from Enterprise to Base, or vice versa
	z		zap explosions (multiple zaps extend further) (E only)

	^R              refresh the screen
	^Z              suspend the game (on a bsd system)
	q               asks if you want to exit this wave (will not work
			    within 10 cycles of previous q command)
	Q		exit this game (not wave)
	?               display a summary of these commands

There may be additional commands listed in your terminal's keymap file.
Unrecognized keystrokes are ignored.  IF YOU FORGET ALL THE OTHER COMMANDS,
REMEMBER "?", which gives you help.

Commands for moving the Enterprise may operate in one of two ways.  If it
is in impulse mode, movement commands affect the position of the ship;
if it is in warp mode, movement commands affect the velocity instead.
The Base always moves in impulse mode.  Since multiple commands may be
entered in one turn (if you can type fast enough), it is possible to jump
over things even in impulse mode.  In a crowded universe this may be the
only way to go.

(Actually, motion commands always change the velocity--the actual motion
does not occur until the next turn.  Impulse mode simply causes the
velocity to be zeroed out at the end of every turn.  Phaser commands, on
the other hand, are executed immediately.  If you want to move and fire a
phaser, you must wait for the motion to actually occur before typing the
phaser command, or the phaser fires from your old position.  This is a
feature, not a bug, and is intended to reflect reality.  Really.)

If multiple torpedo launching commands are given in a turn, a single torpedo
is launched with extra velocity.  You can thus launch photon torpedoes over
objects in the way, and get them where you want them quickly.  This feature
works well with the destruct button.  Variations on this may be useful
against the Space Amoeba.

NOTE:  Phasers destroy the target by blasting the projected next location of
the object hit.  This means that if the object hit, be it Klingon, Romulan or
Enterprise, changes velocity in the same turn, it can elude the effect of
the phaser!  (Note that this also means that if you phaser a Klingon or
torpedo that is about to ram you, you will be phasered as well as he/she/it.
This can be embarrassing, not to mention deadly.)  Smart players move
immediately upon phasering something at short range, or whenever they
think they might get phasered (in other words, most of the time).

Objects with larger mass can bounce objects with smaller mass out of the way.
In a crowded universe the bouncee can bounce quite a way before finding an
empty place to land.  If you let the Tholians fill up the universe with web,
so that there is no place to bounce to, the Tholians win that wave.

The status line across the top gives the current mode, the number of
points accumulated this wave, the Enterprise's energy and torpedoes, the
Base's energy and torpedoes, the number of stars, the number of enemies,
and the stardate.  You will note that nice things happen to your energy levels
when you put the Enterprise next to the Base, or the Base next to some stars.
Bad things happen inside an Amoeba.

An object is destroyed when its energy goes negative, either from a direct
hit, or from the blast of the previous turn's explosions.  Enemies and
stars start with random amounts of energy.  High energy enemies can go warp
2.  A Romulan with sufficient energy maintains a cloaking device.  Tholians
spin web, Gorns shoot homing torpedoes, and the Planet Crusher munches
anything in its way, even Apollo.  Apollo won't let you go unless you kill
him, but he loves you very much and beefs up your shields considerably.
Both Apollo and the Planet Crusher recharge themselves, so you must hit
them hard in a single turn to do them in. (Yes, the Planet Crusher must be
shot in the mouth--he can only die of gluttony--and he blasts out of his
mouth when he dies.)  Tholian web may be crossed only by coasting across it
in warp mode, or by blasting it (but web blasts extend twice as far as
normal blasts, so keep your distance).  The Space Amoeba sucks energy and
grows, and you must destroy the nucleus.  Somehow.  There are at least four
ways.  Phasers won't work on the big ones.

Pirates turn inhabited star systems into uninhabited ones.  Even Friendly
Freighters will take potshots at you if you get them mad enough.

Note that because of the size of the Base's turbo-lasers (the Base does not
have phasers) they cannot shoot anything next to the Base.  (This is why the
Death Star died!)  In part, this is to protect the Enterprise.  It also lets
you shoot over one adjacent star.  The Enterprise's phasers will shoot over
a arbitrary number of adjacent, contiguous stars, including inhabited ones.
Phasers die away with distance, so don't expect them to kill everything with
one blow.

While the Enterprise's shields are up (when it is displayed as "E" rather
than "e"), hits on it count only a fifth as much (or even less if you are
moving in warp mode).  The shields are automatically maintained as long as
there are more than 500 units of energy for the Enterprise.  The Base also
has shields, which stay up as long as it has at least 1000 units of energy.

Aside from losing energy, the Enterprise can also take damage, either random
damage from getting blasted, or specific damage when a system is in use
and breaks down under the load.  In place of the score you will see the
Estimated Time to Repair.  Sometimes docking helps to get things fixed faster.
If you lose both your warp and impulse engines, try the tractors.  The
Base doesn't take damage because it has much more redundancy than the
Enterprise.

You get points for destroying enemies and hostile torpedoes.  At the end of
a wave, you also get bonus points for saving stars, saving the Enterprise
and Base, and for having an efficiency rating higher that 0.8.  You get
NEGATIVE bonus points for letting friendly life forms get blown up, and for
giving up.  Bonuses tend to be scaled by the ratio of the number of points
you got over the number of points you could have got.  If you think you are
done with a wave, but it won't quit, there may be homing torpedoes that you
haven't destroyed--you must make the universe safe for posterity, you know.

When you have used up your Enterprises and Bases (or quit), your score will
be posted to the scoreboard.  You may see the scoreboard outside of the game
simply by giving the command "warp -s".

If you get bored, you can always play with some of the undocumented switches
that are used to test warp.  Such funny games go on their own scoreboard.
For kicks try "warp -x -d50 -C -\& -G -T -E400 -S5" and then go hide.  Quick.
