Description: In Invasion Force, you control a laser base and must shoot through a moving force field and destroy an alien ship. If you hit a black blob in the moving force field, all your damage to the ship is repaired. Smaller ships fly by and drop bombs on vou. The game ends when you run out of laser bases or you run out of time.
Evaluation: This is a fun game to play. The enemy ship is difficult to destroy and the moving force field is an interesting obstacle to shoot through.
The graphics of the game are unusual The instructions scroll off from left to right after you read them, When the laser base or the alien ship is destroyed, the explosion is shown graphically.
A timer goes from 15,000 to 0. After destroying the ship, the player scores the amount left on the timer. In my best game, I destroyed the ship three times and scored 25,390 points. Can you beat that? Invasion Force requires a 16K memory and is distributed by Reston Publishing.
