Quoted from Bax1:
game looks pretty cool. would love to play one sometime or even pick one up.
The premise of the game is basically a space Invaders clone with a few exceptions:
You start with three bases which have three windows in them all lit up. As defenders get down to you're base the game gives you a verbal "danger" which is the same voicing from games like flash Gordon, centaur, etc.
The Invaders are worth more points as they get closer to the base- there is however a fine line between being safe and then brutally being over run.
The three tanks correspond to the three bases and are numbered as such. When you destroy a tank it kills all of the Invaders that are presently in the air space above the base. The tank Target does not reset right away.
The two Marauders are there just to pick off whenever you get a break in the action. However- shooting the Marauders and all of the tanks triggers a full reset of the tanks and Marauders but it also brings out a UFO. Shooting the UFO freezes all of the Invaders and gives you about 3-5 seconds worth of fully automatic firing rate.
There is no limit on ammunition nor is there a time limit. No holds barred shooting.
There is a definite progression in leveling though. The tanks and UFO can speed up/ slow down and move in very random directions once you start to level.
The targeting system is IR beam and phototransistors and is very accurate.
I have replaced a few of the phototransistors with a part I cross referenced and haven't had any issues. I can provide part numbers if anyone is in need.
