A classic 80's calculator game. Shoot down the invaders.
Digital Invaders originally appeared on the Casio MG-880 calculator.
This is a fast paced action game that will put your fingers to the test.
Invader Speed
Compared to the original calculator game, this game is almost identical but with a few slight modifications as described below. The time given for each stage is the time it takes for one invader to travel all the way across the display and cause one life to be lost.
Digital Invaders Android App:
stage 1 - 6.6 sec
stage 9 - 2.2 sec
interval (score showing) - 1.8 sec
Calculator:
stage 1 - 7 sec
stage 9 - 2.3 sec
interval (score showing) - 2 sec
Since the early stages of the game are quite slow, I decided to increase the speed a little bit (0.4 sec faster at stage 1). This is quite negligible. Stage 9 is virtually the same.
INSTRUCTIONS
The aim is to score the most amount of points by destroying the invaders approaching from the right.
Use the AIM button to match the leftmost digit on the display with any of the approaching invaders. Press the FIRE button to destroy the invader.
If the sum of the shot down invaders is a multiple of 10, the next invader will be a UFO (shaped like an 'n') unless the stage is completed.
The defence lines next to the Aim Digit indicate the number of lives the player has left.
There are 2 levels and each level has 9 stages. In each stage you must shoot down all 16 invaders with 30 shots or less. The speed of the invaders increases with each successive stage. In level 2 the invaders start attacking from one position closer. After completing level 2 the game will return to level 1.
When the game is over, the display shows the stage that the player reached and the score.
SCORING
The high score is shown at the start of the game.
The points awarded for shooting down an invader depend on the invader's position. Starting from the rightmost position, the points are as follows:
Level 1
60, 50, 40, 30, 20, 10
Level 2
100, 80, 60, 40, 20
An extra 300 points is awarded for shooting down a UFO.
