Chris Taylor / Mbed 2 deprecated RETRO-SpaceRaiders Featured

After decimating the enemy forces that have attacked your ship, you are charged with taking out as many of the remaining enemy fighters as possible. 3d space fighter game was initially written while I was testing some 3d routines I was implementing for a flight simulator, but my daughter started playing it and seemed to enjoy it so I added a few sound effects, explosions etc. and so this little game was born.
