System Requirements:
~~~~~~~~~~~~~~~~~~~~
This program requires an IBM PC or compatible with at least VGA.
In general, faster systems will run the program more efficiently.
Sound Blaster Notes:
~~~~~~~~~~~~~~~~~~~~
This program contains routines to play digital sound on a Sound
Blaster or compatible card. However, this program does NOT
contain autodetection routines. This program relies upon the
BLASTER= variable being set appropriately in your environment.
If the BLASTER= variable is set incorrectly, the program may
crash. If the BLASTER= variable is absent the program will
NOT attempt to use Sound Blaster sound.
Additionally you will need to have free EMS memory to hear
all digital sounds (they're too big to fit in conventional
memory). The sounds deemed "most important" to game play
will be loaded into conventional memory on a first-come, first-
served basis. To hear ALL sounds you will need enough EMS
free to fit the file ACKSFX.DBO. Check free EMS with the
MEM command under DOS.

Game Notes:
~~~~~~~~~~~
The object of the game is to destroy as many helicopters and
paratroopers as possible. If a paratrooper lands on the ground
he may still be hit by flying debris, another paratrooper free-
falling on top of him or by your gravity-bound shells.
There are three levels of play: Easy, Hard, and Insane.
You may select the level of play before the game starts.
The game also keeps track of your statistics, how many shots
fired, how many hits, how many choppers and troops hit, etc.
Keep in mind that you have until the START of the next sortie
to try and kill the troops on the ground, using the [G]ravity-
bound shells, or dropping burning wreckage on them. When the
next sortie starts, if there are more than four (4) troops
landed on either side of your base, the game will end.
Ack-Ack Attack is written in C and assembly language, and has
been optimized as much as possible. However on some older
systems performance may deteriorate when there are a lot of
shapes moving on the screen.
