TI Invaders is a Space Invaders clone (perhaps the most cloned video game in history),[1] that was produced for the TI-99/4A home computer system. TI Invaders was programmed by Garth Dollahite, and was released in the 4th quarter of 1981 via Solid State Software Command ModuleTM with part # PHM 3053. The original retail cost for TI Invaders was $39.95. It was distributed and published by Texas Instruments.

Gameplay
Like all Space Invader's clones, the player in TI Invaders controls a laser cannon that moves back and forth, horizontally on the bottom of the screen shooting at an army of descending aliens. Occasionally during the game, a space saucer will hover across the top of the screen which is worth varying points, depending on how close to center it's hit, if hit by the player's laser cannon.
TI Invaders presents several unique features not found in the original Space Invaders arcade game. First off, after a player defeats a wave of enemy aliens, TI Invaders inserts a bonus level where the player shoots at a UFO. With each hit, the saucer changes directions and increases in point value, shrinks in size, and moves upward away from the laser cannon.
Another change from the original is that the aliens change from wave to wave of enemy attacks. The bottom row is replaced on each level with the level above it, and a new top level alien appears. Each different alien type fills two rows of identical aliens. As the game progresses, the newer aliens become more difficult to hit either by becoming slimmer or by becoming invisible at times, only being able to be hit while visible.

Manual
Introduction
Your world is under attack by downright nasty creatures from the black pit of Space. It's up to you - can you save your world from this hostile horde? You must use your wit and quick movements to destroy the multi-colored creatures. But, as you shoot down each attacker, the swarming horde increases its speed and sprays shots at your missile. Your missiles are limited, so you also must be cautious.
Your goals are to:
- attack and destroy the invaders.
- shoot down the yellow control ship.
No sooner have you destroyed all the attackers than the red spaceship appears to challenge you. If you let the ship slip off the screen, a new mass of creatures appears.
A one-player game, the TI Invaders game tests your skills and strategy. Movement on the screen may be controlled from the keyboard or the Wired Remote Controllers.
TI Invaders is available as either a Solid State Software™ Command Module or a diskette-based game. Note that the diskette-based version requires the TI Disk Memory System and must be used with either the TI Extended BASIC or Editor/Assembler Command Module (all sold separately). Follow the set of directions that applies to your version of the game.
