Intruder Alert is a fast paced arcade action shoot 'em up game with
awesome graphics and superb sound effects.
It requires 512K, a joystick and loud speakers!
It runs on the A1000, A500, A2000, & A3000, and has been tested in
AmigaDOS 1.2, 1.3, and 2.04 -- In fact it was developed on the A3000
with 2.04 and an A1000 with 1.3, so it has been thoroughly tested on those.
In August of 1991, Intruder Alert began as a simple demo of men in
striped shirts bouncing around the screen. In 4 months, over forty
Domino's pizzas (pepperoni with extra sauce), 463 Oreos, 269 Chips
Ahoy cookies, 2 broken joysticks, and countless wee hours of the morning
later, it became the game you are playing today.

We will send you a disk with the latest version of Intruder Alert, and a
level editor to add your own levels, and modify existing ones.
Since this is our first Amiga game we have a special offer for amateur
game programmers (like ourselves) - If you send a really large donation
like say $45.00US - we will send you the source code! While the code is
copyright by Eyeballs Software, you will also have a license to use the
code in any of your programs, without paying any royalties - as long as the
source code itself is not distributed (binaries only).
THE GAME
Intruder alert is played with a standard joystick plugged into
port 2, on your amiga. Everything in the game is controlled with
the joystick , with the exception of high score entries. For these, you
type in your name on the keyboard.
After clicking on the Intruder Alert icon, the intro screens will come up,
and when they are done the title will be flashing on the screen. Press
the joystick button to continue.
The theme song will then begin playing, and the screen will have four big
buttons on it. Using either the joystick or the mouse select which
section of the game you want to play as follows:
.-----------------. .-----------------.
| | | |
| Easy Levels | | Hard Levels |
| | | |
| | | |
| | | |
| | | |
| | | |
`-----------------' `-----------------'
.-----------------. .-----------------.
| | | |
| Jay's | | Dave's |
| Custom | | Custom |
| Levels | | Levels |
| | | |
| (quite hard) | |(also quite hard)|
| | | |
`-----------------' `-----------------'
Highlight screens from these level sets are:
Hard 27: Ready to Die?
40: Make Tracks. Beat Feet. Move It. RUN!
48: Somewhat Sequential
49: Last But Not Least
Jay's 4: The Flying 'V'
10: Banzai Mission
18: Looks Like Trouble
20: There Can Be Only One
Dave's 1: Welcome To The Machine
3: I Hate Life
10: Helter Skelter
16: Arc De Flee-omph
We consider these levels to be the epitome of Intruder Alert desperation.
When you select the easy levels, the titles of the levels will explain
the mechanics of play. The other sections will have titles that are
a bit more, shall we say, unusual. It's probably best to start with
the easy levels; you'll get the hang of it rather quickly.
We spent the most time developing the hard levels - so these should be
more difficult, but also playable for the average joystick junkie.
At the start of each level, your man will flash, and the action will be
stopped. When you are ready to go, press the FIRE button.
Shoot anything that moves, and don't touch any walls! (SHWAD)
Watch out for Homer. He moves, but you can't shoot him! He is easily
recognized by his trademark cry: "Oh No !"
The object of the game is to complete all of the levels!
At this point we must point out that the Jay & Dave custom levels are
actually quite difficult, and only die-hard Intruder Alert fans will
complete them all. (rest assured that either Jay or Dave has actually
completed each and every level, so they are ALL possible, if not probable).
But since these levels can be quite frustrating, we have provided the
following mechanisms, to make them more enjoyable 8->
CHEATING:!!!!!!!!!
Yes, it's Intruder Alert - the game that lets you cheat !!
At any time during the game, you can press the following keys to help
you out. Of course, if you use any of these cheats, you will not be
allowed to enter a high score.
'S' - Skip this level
'A' - Skip a lot of levels!
'L' - Give me some more men!
An excellent strategy for tackling the more vicious level sets is to juice
your lives up ridiculously high and skip to the tough screens. Rehearse these
until you've gotten them completely "wired" and then start from level one to
get on the high score board.
CONTROL
Joystick Left - Move "Little Guy"(tm) left.
Joystick Right - Move "Little Guy"(tm) right.
Joystick Up - Move "Little Guy"(tm) up.
Joystick Down - Move "Little Guy"(tm) down.
FIRE - Fire a shot in the direction the
"Little Guy"(tm) is facing
Diagonal movement and firing are also possible.
Keyboard 'S' - Skip this level*
Keyboard 'A' - Skip a lot of levels*
Keyboard 'L' - Extra Lives*
Keyboard 'F1' - Quit and return to level selection screen
Keyboard 'HELP'- Kill the rest of your men.
Keyboard 'ESC' - EXIT THE GAME
(tm) Little Guy is a trademark of Eyeballs Software.
* These options will prevent you from being on the High Score board.

The Authors
(Who are these Eyeballs guys, anyway?)
Jay Stelly is the primary programmer for Eyeballs. He has a BS in
Electrical Engineering (Computer Option) from the University of Southwestern
Lousiana. He earns a living writing insurance rating software for PCs. 8-(
He is also responsible for the music and sound effects design in Intruder
Alert. Jay is responsible for everything tight and efficient about Alert.
Dave Speyrer is the Artist for Eyeballs. He will be receiving a BS in
Electrical Engineering (Computer Option) in May 1992. He drew all of the
graphics (Except for the zombies which Jay drew, and Dave doesn't want
credit for!) in Intruder Alert. He is also responsible for for some
algorithm design and coding, but mostly everything pretty and nitpicky.
Dave and Jay have been writing games together since 1985. Although this
is their first game for the Amiga they have written other games (that
you probably never heard of) 8-) for other platforms including:
As Digital Worlds Software:
Knok*Out Boxing - Radio Shack Color Computer
The Lair of Erebus - Radio Shack Color Computer
Taos: The Summoning - Apple II
The Astral Gate - Apple II & Radio Shack Color Computer

in assembly for speed. (again with SAS)
The art was done using Deluxe Paint IV - Electronic Arts
The iff.library - by CHW (sorry I only have initials) was used to
load pictures.
MED & medplayer.library - by Teijo Kinnunen was used to edit the music.

Bruce Dawson (of CygnusSoft Software). was used in the level editor.
