Atomic Galaforce by Kees van Oss, 2012

The classic shoot-'em-up Galaforce was originally released on the BBC Micro and Electron in 1986 by Superior Software. Coded by legendary Acorn programmer Kevin Edwards, he has unearthed and generously shared the source code of the original BBC Micro version with RS and the first attempt to port the game is by our talented Atom coder Kees van Oss.

8-directional movement of the player's spaceship; fast and slow-speed bombs which home in when later zones are reached; keyboard and joystick control; self-play demo mode; high score table and superb atmospheric music.

In the midst of the 25th century, the United Cosmological Federation declared war on the savage, belligerent aliens inhabiting the Magellanic galaxy. Only the most experienced of the U.C.F. pilots were chosen to embark upon the perilous mission of conquering and overthrowing the hordes of Magelian, the Galaforce.

The Galaforce aliens attack in precise preconceived formations with each zone comprising several such formations. You must pilot your spaceship carefully avoiding the aliens, or shooting them whenever possible. Some aliens have to be hit more than once to destroy them. You have four spaceships and an extra spaceship is awarded if your score reaches 20,000 points.
