TI Invaders is a fixed shooter video game published by Texas Instruments in 1981 for the TI-99/4A home computer. The game is a Space Invaders clone where the goal is to shoot all of the aliens before they reach the bottom of the screen. TI Invaders is part of the TI Arcade Game Series which includes Tombstone City: 21st Century and Car Wars.[1][2]
Gameplay
[edit]TI Invaders is a single-player fixed shooter. At the start of the game, the player is face with an enemy fleet eleven creatures wide and five creatures deep.[3] With the joystick or keyboard, the player moves a laser base (called a missile in the manual) left and right, pressing the fire button to shoot lasers at an 11×5 grid of invaders. Shooting different invaders scores different amounts (see below). As the number of invaders dwindles, they increasingly move faster. Upon shooting the last invader, the player moves on to a bonus round before the next level. As in Space Invaders, which TI Invaders is a video game clone of, a UFO will appear once or twice a round and travel from one end of the screen to the other. The player has the opportunity to hit it to score bonus points, the amount depending on where the UFO is hit.
There are two difficulty levels to choose from:[4][5]
- Merely Aggressive: invaders fire semi-randomly, targeting the player only sporadically
- Downright Nasty: invaders fire rapidly and deliberately at the player and their point values are doubled
Bonus round
[edit]After each level is cleared, there is a bonus round consisting only of one UFO. The UFO travels slowly from one end of the screen to the other until it is hit for the first time, then it returns other way at twice its original speed. The player must track it to the other side of the screen and shoot it again, making the UFO return in the other direction again. The UFO's score value increases gradually with each hit, and the UFO gets smaller and smaller. This continues until either the player eliminates the UFO completely, or it escapes off the screen.
Bonus missiles
[edit]After earning 3,000 points the player receives an additional missile. Thereafter, at every multiple of 10,000 points, one damaged missile is repaired and again usable. (When a missile is damaged, it rolls off onto a small elevator and off to the right of the screen, and one of the extra missiles rolls onto the elevator from the left hand side and takes its place. When one is repaired, it moves from the damaged end to the extras end fully repaired.)
End of game
[edit]When the last missile is destroyed, the closest invader to the bottom then goes down, clears away the area the extra missiles and damaged missiles were, writing "GAME OVER" in the middle of it all, then it and the rest of the remaining invaders on the screen jump up and down, as if laughing or cheering. If both the last invader on the screen and the last missile are killed at the same time (which is not an uncommon occurrence at any time in the game), the next set of invaders will immediately appear on the screen, with again the invader closest to the bottom doing the game over routine.
Also, as in Space Invaders, if any number of invaders hits the bottom row, the closest one to the missile will shoot it from the side and the game is over regardless of the number of reserve missiles left.
Reception
[edit]Lawrence De Rusha, Jr. for InfoWorld said "I found this game very entertaining and a challenge to play. Because the options, including the various screens, allow for a wide range of skills and because the level comes harder as you progress, the game has lasting value."[6]
Dick Olney for Personal Computer World said "I long ago tired of this game in the arcades, but having such a good version in my living room did rekindle my interest. If you haven't already spent your quota in ten pences then you'll probably find this module good value for money."[7]
Unofficial 99/4(A) gave the game two stars and said "All I can say is that the aliens keep coming, you shoot them down, they shoot at you, and a space craft flies by. All good fun if you are into that kind of game. Yawn ..."[8]
In 1982, TI Invaders was listed as one of the top-selling computer games for the TI-99/4A along with Hunt the Wumpus.[9]
