ASTROBLASTER / AD INFINITUM
(c)1983 Shaun Southern/ Mastertronic
-------------------
This game was published initially as "Ad Infinitum" (in the US?) 
by Mastertronic. Probably was published in Europe as 
"Astroblaster" due to conflict of name with another game made in 
England. (But there is now a conflict with a pinball game!)

From the Author:
"This program was written by Shaun Southern over a period of ten 
weeks... it seemed longer..! It is comprised of 256 different 
screens of aliens attacking in formation." 
(This was an early game by Southern, known for other games.)
-----------------------------------------------------

Use a joystick in either port to move and space or fire to shoot 
the aliens. You start with 6 lives. 

You will lose a life 
--- if you are hit by an alien or a bomb, 
--- if your laser overheats or 
--- if you run out of fuel. 

Double points are awarded if your fuel status goes critical. 

In-between levels you must dodge asteroids, but collide with 
fireballs for extra fuel. You cannot shoot asteroids. Also dock 
with the mother ship to refuel but don't hit anything!

Find out how to earn secret bonuses on each level. 

You can pause the game while the aliens are attacking by pressing 
"Q". Press Q again to restart. 

The level you are on is shown in hexadecimal notation instead of 
a decimal notation to make it fit on the screen... 

Continuation Option:
After the game is over you can press "C" within 5 seconds to 
continue the game that has just been played with six extra lives 
for each player. If you do not press C then the high score screen 
will appear, and then when the game is restarted the scores and 
levels will be reset. Scores achieved using the continue option 
are not eligible for the high score screen. 

If you complete all 256 levels with only six lives you will 
receive a "large" bonus.... 

Select number of players (1 to 4)
Press F7 to start.

only six lives let me know!!!!
