Galactic Invasion is the main game for Round 11 of the Astrocade High Score Club. Round 11 will last about three weeks. The round ends on Sunday, October 2'nd at 8pm MST.
Galactic Invasion is a 4K game released by Astrovision in 1981. It is part of the Action/Skills Series. The game was originally released on cartridge as Galaxian. If you know who programmed this game, then let us know.
Galactic Invasion Instructions
Alien ships come at your missile launcher from every direction. They peel off from their formation singly or in groups of two or threes. The more aliens you destroy, the more of their reinforcements attack. Each ship is piloted by a highly skilled captain capable of maneuvering with incredible agility. Realistic sounds add to the intensity! Up to 4 Players.
Galactic Invasion (1 to 4 players)
Aim your missiles at the alien ships and score points for each one you hit! The colorful invaders spin around and soar across the screen in an attempt to destroy your base.
Excitement builds as they collide into (or bomb) one after another of your bases. Exploding several of their ships will make the aliens angry-- they'll attack you with greater speed and force than ever before.
Starting the Game
Choose Galactic Invasion by pressing 1 on the keypad or by using remote game selection (pull the trigger on hand control #1, turn the knob until 1 appears on the screen, then pull the trigger again).
Select the level of difficulty (0-9). At the easiest skill level (0), the alien ships destroy your base by crashing into it. As the levels become more difficult, the action becomes faster. At level 4, they start dropping bombs. With the higher levels, you engage in battle with more and more aliens at one time. They drop a larger number of bombs and descend with greater speed. By the time you reach level 9, it is next to impossible to survive the battle.
Choose the number of bases (1-9). You will have one base at a time which you will use as your missile launch pad. Your base will be shown on the lower part of the screen.
Enter the number of players (1-4).
Playing the Game
The hand control functions for Galactic Invasion are:
Trigger - Releases your missiles.
Knob - Has no function.
Joystick - Moves your base left or right.
The object of the game is to reach the highest score by destroying as many alien ships as possible. You'll have to move quickly to avoid the ships which peel off from their formation in groups of one, two, three or four.
After you select the number of players, the alien ships will immediately appear on the screen and will start descending on your base. Fire your shots quickly and take evasive action to avoid their ships.
When you have shot down all but one of the aliens, the remaining ship will become enraged. It will attack with such fury that you'll have to move quickly to avoid it.
If you manage to shoot down a complete set of ships, you will hear the sounds of another troop coming to battle. Since the aliens will always be joined by reinforcements, you cannot hope to destroy them all. However, as your skill increases, you will be able to achieve higher and higher scores.
At the top of the screen, you will see each player's number and score. The current player's number is highlighted in a different color. Players take turns firing at the aliens until all bases have been destroyed. The number in the center shows the remaining bases for each player.
When your missile hits an alien ship, points are awarded based on the position of that ship. The point values for the ships, from top to bottom, are:
In rack - 10
Diving with no escorts - 15
Diving with 1 escort - 20
Diving with 2 escorts, - 30
with at least 1 still diving
Diving with 2 escorts, and - 80
neither still diving
In Rack - 5
Diving - 10
In Rack - 4
Diving - 8
Strategies for Winning
If a top row alien is hit during a dive, the ships will be stunned temporarily and they will cease firing for a moment. Take advantage of this time to move your base and fire another shot.
Also, the alien ships only drop bombs after their altitude is below the middle of the screen. Fire quickly and you will score more points.
To play Galactic Invasion again, press the RESET button and follow the instructions for starting the game.

Here is a video review of Galactic Invasion by Nice & Games:
The play settings for [b]Galactic Invasion, are:
Skill Level - 4
# of Bases - 4
Skill level 4 is the first setting where the alien ships start dropping bombs at you during gameplay.
As usual, 10 points can be earned this round (excluding bonus points).
Galactic Invasion Bonus Points
There is just one way to score bonus points for Galactic Invasion:
1) High Score Reached on Level 9 with only 1 Base - 1 point to the player who earns the highest score with just one ship on skill level 9. This level starts out brutally-- the aliens fire so many shots that it is nearly impossible to avoid them!
Outpost 19 (BASIC Bonus Game)
This round's bonus game, Outpost 19 by WaveMakers, is a BASIC game released in, I think, 1983 on Tape 19 (with Music Keyboard as the "b-side"). This was later reprinted in Arcadian 7, no. 2 (Dec. 20, 1985): 30-31. A bug fix was printed in the next issue: Arcadian 7, no. 3 (Mar. 21, 1986): 35.
You can download the AstroBASIC version of Outpost 19 here:
The official documentation for Outpost 19 has not been archived. However, when the program was printed in the Arcadian, George Moses provided detailed instructions:
How to Play Outpost 19
You are stranded on an alien outpost with nobody to help you. While you wait and pray for a rescue party, the only hope you have of surviving is to gather the food parcels that exist in each of the 16 rooms of the outpost. A pull of the trigger will show you a full screen map of the outpost. The rooms with food parcels stashed will have room numbers. After you pick up a room's food parcel, that room will appear on the map as a blank room.
While you're chasing after the food parcels, the alien is chasing after you! His advantage is that he can go through walls, so his path toward you is more of a straight line, while your escape must be around obstacles in the rooms and through doorways provided. But you have a couple of aces in the hole. (1) You have the trigger-pull top-view map which also shows you which room the monster is in and where you are. (2) You have a transporter in each of the odd-numbered rooms! They're usually in the lower parts of the room. After you've played a few games you'll remember where they all are.
To become familiar with the workings of the transporters, look at the room map in this issue.
The large numbers are the numbers of the rooms containing the transporters. The small numbers are the numbers of the room you will transport to. Example: If you are in room 13 and just as the alien monster is ready to pounce, you nonchalantly step into the transporter. Poof! You'll find yourself in room 8. That's clear across the outpost and you've bought some time to hunt up some more food parcels before he can catch up to you.
How to Die
There are two ways you can get killed. (1) The monster touches you. (2) You try to grab a food parcel while the monster is in the same room (use your trigger map to see if he's coming before you grab the parcel). If you die, pull the trigger and start a new game.
This is one of the best "AstroBASIC" programs I've ever seen! And the only one that surpasses this is a Blue Ram BASIC version Mike did. It fills a 16K Blue Ram and has fantastic graphics, action and constant music. If you're interested, we can print it in a future Arcadian. Unfortunately, Mike Peace has packed his Bally Arcade away in a box somewhere and is presently programming on a (gasp, choke) Commodore-64. But, he gave us permission to print this program and some other previously unreleased tapes we'll print in the future.
Transporter Note [From Adam]
You'd think from the game's description that George Moses gives that you'd be able to find the transporters with no problem. That's not the case. As far as I can tell, the transporters seem to be invisible. I've only found one of them (in the first room that you start the game in), and it did transport me across the outpost-- but I had not idea that I was entering the transporter until I teleported.
As George Moses mentioned above, Outpost 19 was also released for Blue Ram BASIC. It looks much more like a cartridge game, as can be seen in this screenshot:
Dave Carson reviewed the BRB version of the game in his column Extended Memory Products Review, Arcadian, 6, no. 11/12 (Oct. 31, 1984): 118-119. You can read the review here:
If you have at least a 16K RAM expansion, then you can play the Blue Ram BASIC version of the game, which can be downloaded here:
The BRB version of Outpost 19 is also on Ken Lill's multicart (the UltiMuli Cart)-- but it still requires extra RAM to play the game. Also, I've run into some syntax error issues when playing the game from the multicart.
Outpost 19 Bonus Points
1) Playing Outpost 19 - You get a bonus point just for playing Outpost 19.
2) Outpost 19 High Score - You can earn another bonus point if you get the highest score for this game.
3) Video of Outpost 19 - To continue to promote Astrocade BASIC programs, a bonus point will be awarded to the first person to upload a video of Outpost 19 containing a full game. If the video is a video review, then you'll earn two points!
Please post all of your scores for both games here. Scores posted on the Bally Alley discussion group will no longer be accepted. If you post a video score, then please note the score obtained in the video-- as this makes it easier for me to keep track of all the scores.
Have fun defending the Galactic Empire (or whatever it is you're protecting) in Galactic Invasion and find your food and avoid the baddie in Outpost 19.
