INSTRUCTIONS
~~~~~~~~~~~~
You control the ship at the bottom of the screen, use keyboard or joystick
to move left and right. Shoot the aliens and then catch the coins to earn
money. There is a variety of aliens, weaker on early levels, stronger on
later levels. There are silver coins and golden coins. Golden coins are
worth the same as 2 silver coins.
On the right-hand side of the screen are the power-ups. You can buy
power-ups with the money you earned. The items you can afford are indicated
in blue. The items you do not have enough money for are grey. Use keyboard
or joystick to move the cursor in the power-up bar up and down. Press the
buy-button to buy the selected item. When you buy an item it becomes
yellow, indicating how much ammo or time is left for that item.
Item Description Price
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Speed-up Move faster 10
UZI Gives you more firepower 30
Plasma gun Spreads as you move from left to right 40
Magnet Attracts coins 50
Boomerangs Returns to you after you shoot it 60
Grenades Explode on impact, causing much damage 70
Scattershot Shoots in 5 directions 80
Laserbeam Shoots right through aliens 90
Shield Makes you temporary bullet-proof 100

In the top left-hand corner you can see your score, how much money you've
collected and how many ships you have left (excluding the active ship). The
game is over when you loose your last ship, or when you've finished all 100
levels.
Every 10 levels there is a bonus level. In bonus levels, the aliens are
marked "1", "2", "3" etc. You must shoot the aliens in the correct order,
starting with 1, then 2 etc. You get more and more points for each alien.
If you shoot the incorrect alien the bonus level ends immediately. Also try
to shoot the UFO's that appear at the top of the screen to score bonus
points. To find out the cheatcodes, you must complete all 100 levels.
You move the cursor through the mainmenu and optionsmenu with the same keys
as you move the power-up cursor up and down. You select a menu item with
the fire-buton or the buy-button. You can customize the keyboard controls,
by default the keys are as follows.
Default keys:
~~~~~~~~~~~~~
Move ship left - Cursor-left
Move ship right - Cursor-right
Move powerup-cursor up - Cursor-up
Move powerup-cursor down - Cursor-down
Fire - Spacebar
Buy item - Enter/return
Pause game - Escape
Exit game - When paused, press Escape again
From the main menu, if you don't do anything for about 30 seconds the
program will go into "attract mode". It will cycle through the
title-screen, instructions, high-scores and the credits-screen.

KNOWN ISSUES
~~~~~~~~~~~~
On Windows NT and Windows 2000 there is no sound in any MS-DOS application,
so Cash Invaders is silent on these systems unless you install VDMSound
(http://ntvdm.cjb.net/). VDMSound emulates a soundblaster for MS-DOS
applications running under Windows NT and Windows 2000. On Windows 95,
Windows 98 and Windows XP there should be no soundcard problems, as long as
it is properly installed.
Joystick is not supported on Windows XP, it only works when you have
Windows 95 or Windows 98 or ofcourse MS-DOS.
A minor issue, if you use the joystick and un-plug it while playing or in
the menu's, the program locks up. To program will continue when you plug
the joystick back in, but better is to simply.. NOT DO THAT! :P

BACKGROUND INFO
~~~~~~~~~~~~~~~
Cash Invaders is my first big game.. yay! It was inspired by Space Invaders
(Taito 1978), Blood Money (Psygnosis 1989), Astro Fire (ORT Software 1994)
and Space Bastards (Didier Dambrin 1996) and some other games. It was
programmed in Borland Pascal 7.0, the graphics were created with 3D Studio
Max 4.2. The sound effects were taken from numerous sources (using
www.google.com) and edited with CoolEdit2000. The development was started
in november 2000. Due to long periods of inactivity it took quite a while
but it was finally released in december 2002.
Cash Invaders is freeware, so feel free to copy and redistribute the game
as much as you like, as long as all files remain unchanged.
