Gameplay
The player in Slymoids controls a cowboy tasked with fighting off the "Slymoids" armed with his trusty pistol. These creatures approach the player either from the horizon or from the sky. The player can shoot up at the Slymoids descending from the sky, or side to side at those approaching from the horizon. The player can control his/her cowboy moving either left or right in search of the enemies. The game takes place in three different locations: 1. in a city, 2. along the coast line, and 3. in a cavern. The player gets to choose from 4 different levels of difficulty to begin the game.

Fun Facts
- Texas Instruments was concerned that the theme music that James Von Ehr II created for the game was actually stolen from another source. He had actually created it years earlier on his home-built analog synthesizer controlled by his Apple II computer. [3]
- Programmer James Von Ehr II placed a couple of Easter Eggs in Slymoids. Inside of the castle around the swords that hang on the wall can be seen the initials JVONEHR and GVONEHR James and his wife's (Gayla) initials. Gayla is credited by James as having offered helpful design suggestions for the game. [4]
Manual
Introduction
In this one-player game, you are a sharp-shooting cowboy-the last defense against the hordes of alien Slymoids. Use your Slymoid Scanner and Laser Fireball Weapon to locate and destroy these strange life forms. The devious Slymoids also appear in two other forms-Jelloids and Spores. Chase the Slymoids through fields, castles, and caves. But beware! The crafty Slymoids have turned spiders, bats, and even rocks against you.
With Slymoids you can:
- Experience multi-screen graphics
- Enjoy graphics that create a 3-D effect
- Choose from 5 levels of difficulty
- Use Wired Remote Controllers (joysticks) or keyboard control
- Hear special sounds that warn you a creature is about to appear
Playing the Game
When the game begins, you are located in one of three battlefields: a grassy slope, a castle, or a cave. You can destroy some creatures with a single shot. Other creatures must be shot several times before they are eliminated. As each battlefield is cleared of Slymoids, you move to another location. If you are victorious, you progress to the next level of difficulty. Destroy all the Slymoids before they overcome your cowboys.
