Shootout At The OK Galaxy is a cross platform 3D space fighting game from the Avalon Hill company's Microcomputer games division (they were originally a board game and strategy pen and paper game company dating back decades earlier). This was author Britt Monk's first game that he programmed for Avalon Hill (after doing a few independent games that he sold himself), and he ended up doing several Coco ports (or Coco originals) for the company. For this game, to get the most color (and an easy way to draw the text on the screen, especially on the map), Britt chose to use the SG6 mode (64x48) - which is slightly higher resolution than SET/RESET low res graphics in BASIC. At the time of this writing (June 12, 2023), not all emulators seem to be playing the sound correctly, so be forewarned.
The game itself has the 15 skill levels to choose from, and the player is on a mission to destroy up to 30 alien warships, flying between different sectors. It bears some resemblance to Atari's famous Star Raiders, which itself was cloned on the Coco from Tandy with Project Nebula, but more colorful. To warp between sectors the player must have their azimuth properly set to 0 (done by moving vertically). To look at the long range map, the player hits the M key and it gets overlaid on the viewscreen. There is a single starbase in the game that you can get to to recharge your ship (if you run out of energy, you die... and energy is used for Hyperspace travel, firing, and shields). Unlike Project Nebula, this game will run fine with a single joystick (and some keyboard keys).
It should be mentioned that when the game was completed for Avalon Hill, they gave Britt permission to sell a small number of "signature" editions straight from Britt himself, which he signed and sold for $22.00.
