History:
--------
Hi, and welcome to the exciting world of Cosmic Aliens !
This program has come a long way since its early beginning in my
Basic 2 class at Prospect Hall College way back in March of 1988.
Since then, I have added all kinds of new features and stuff.
The game started on a monochrome PC clone and it was just a B.S. program
I wrote. I told my friend I could make a space invaders game, and he didn't
believe me, so I started, first with the ship (the easiest), and all you
could do was move the ship left and right, then, I added the alien
(just one !) and it randomly drifted across the screen.. but before you
know it, I started incorporating all kinds of neat logic and features, making
the game more fun.
I then added the graphic title screens and such, I used "THEDRAW" an ansi
screen editor program, then saved the graphics in ascii format, which was
easily loaded into the Quick-Basic compiler, then I converted them into
strings that could be printed on the screen with different color patterns..
and from there, we have all the makings for a high-quality arcade game !
Loading the Program
-------------------
To load the game, type "ALIENS" from the DOS prompt. The game will
start out with the introduction screen, which will contain any new
information about the particular version of Cosmic Aliens you are playing.
Press any key to go to the TITLE SCREEN.
The Title Screen:
-----------------
From the title screen you have a few options open to you.
Press "S" to turn the sound on or off, "Sound On" will be indicated by the
familiar "Star Wars" theme. Also, the current movement device, either
Joystick or Keyboard will be displayed. To Switch Devices, press "J" for
joystick movement and "K" for keyboard movement. If you are using the keyboard,
press the left and right arrow keys to move left and right, and the space bar
to fire lasers. If you are using the joystick, move the joystick left and
right, to steer your ship, and press the lower button to fire. If using the
joystick, the Joystick must be Calibrated. This is a method used to read the
joystick values (left, right, and center). Different computers and game cards
all register different values from the joystick port, so this is done to
properly adjust your particular joystick set up.
After you have selected the movement device, and the sound on/off,
you are ready to play the game. Press a number key 0-9 to start on the
desired difficulty level.
One other option available from the title screen and to be described in
further detail in the next paragraph is the Options Menu, press "O" from the
title screen to enter the Options Menu.
Options Menu
------------
The Options menu is entered by pressing "O" from the title screen.
From the Options Menu there are the following options available to you :
[D] adjust defaults
[R] Re-calibrate joystick
[M] modify Difficulty Level
[X] Exit from Options Menu
Press "D" will bring you to the defaults menu, which will allow you to
change a lot of the default values used by the game, such as the number of
men, the points required for free men, the length of time before the game
speeds up,and other options.
Option "R" allows you to re-calibrate your joystick, in case the initial
values do not cause the movement to perform properly.
Option "M" will allow you to modify the number of aliens and their speed
for each of the 10 difficulty levels 0-9. Do this by first selecting a level
you wish to modify, by pressing a digit 0-9, the level # will be displayed on
the top of the screen as well as the number of aliens and their speed.
Press the "+" and "-" to speed up or slow down the aliens, the speed is from
1 "fast" to 99 "slow". Use the left and right arrow keys (or 4 and 6 on
your keypad) to in/decrease the number of aliens, from 1 to 30. when you have
reached the desired number of aliens and speed for that level, hit [ENTER]
to record your values into memory. From there, either select a new level, or
hit the <ESCape> button on your computer to return to the options menu.
And, when you are done with the options, hit "X" to return to the title
screen.
How to play the game:
---------------------
Currently, there are three different phases of the game, in future releases
there will be added rounds and such, but as for now, let us discuss the
phases currently supported by the game.
The "ALIEN" Round
-----------------
The Alien rounds make up the game.. those are the rounds where shoot at the
aliens.. The basic strategy is to shoot at the aliens "" and avoid
getting hit by their bombs. Hitting an alien is worth 100 points, and if you
hit the bombs, they are worth 25 points.
As the game progresses, the number and the speed of the aliens will
increase. On high levels, a "KAMIKAZE" alien attack may occur from time
to time..while in this mode, the normal alien attack will temporality clear
from the screen and one or two Kamikaze aliens will be frantically dropping a
rain shower of bombs towards you. Try your best just to stay out of their
way.. If, however, you do manage to hit the kamikaze, he is worth 1000 points,
and if all Kamikaze aliens are destroyed before the Kamikaze attack ends you
will automatically clear that wave and advance to the next level.
To offer bonus points, and to provide good target practice, alien UFO's
will zip across your screen from time to time offering 100-1500 points for a
direct hit. After you have shot all the aliens on the screen, you will be
advanced to the next round, and the game play will continue.
Asteroid Shower
---------------
In some cases, before a new round can be reached, after clearing a previous
round, your ship will come across an "Asteroid Shower" during the hyper-warp
to the next round.. when this happens, you will be back on the screen. This
time, your goal is to hit a given number of UFO ships in the middle of the
asteroid shower.. this can provide somewhat of a challenge.. the asteroids
are falling in a random rain-shower formation, causing both deflection for
the UFO ships, as well as an obstacle course for you to dodge..
The asteroid rocks can not be destroyed.. your lasers are absorbed and have
no effect. And, on higher rounds, you are required to hit more and more UFOs
before you can clear the shower. The Asteroid Show round only last a short
time, and If you have not hit the required number of UFO's before the round
ends, you will loose one ship, and then be sent to the next round.
Bonus Round
-----------
Every 5th Round will begin with a "Bonus Round". In this round, you will
have a given time frame to hit as many UFOs as possible. You can not be
hit or destroyed in this round, it's only purpose is to offer you a chance
to gain more points and perhaps a few free men.
High Scores
-----------
If you have played a great game, you will have a chance to enter your name
in the Cosmic Aliens Hall of Fame.
Pausing and Quitting the Game
-----------------------------
During any of the game phases, pressing the <ESC> key will put you in the
pause mode. From the pause mode, you can either press "C" to continue the
game, Press "Q" to quit the game and return to the title screen, Press "E"
to exit the game to dos, or press "B" for the BOSS MODE, which is actually
a DOS shell where you can perform commands at the dos prompt, enter the
command "EXIT" to resume the game play.
Future Releases
---------------
I have big things in the works for this game.. I am working on new rounds,
extra features.. support for color graphics, and even full stereo music
sound tracks on the Ad-Lib music card... but, I need your support..
I know you've heard the plea a million times before.. but I feel this
program could grow to be something real big, with strong user support...
I always take comments and suggestions, and try to implement them.. I have
a large number of play testers/debuggers who play away.. then come back and
say "change this", "add this", "take out that", and with support like that,
and FINANCIAL SUPPORT, I can continue to let this game grow..
If you would like to become a registered owner, entitling you to future
registered releases.. please contact me by phone or mail.

What can I look for in future releases ?
----------------------------------------
Extended support for networks (currently testing NOVELL and NTNX)

music Multiple players (2-4 maybe more, especially on networks !) Mouse
Support (don't hold your breath, that's a bitch right now) "SMART" bombs,
shields, hyperspace... and more.. more.. more !!!
As you can see, I've got big plans for this baby.. please support this game..
I don't want to be forced to sell it to a company and make it copy right.. I
believe that with local user support, I can offer a fine product, without
charging like 30 bucks and adding copy protection.. so please... help out !!
