Space Invaders

Space Invaders is an implementation of the classic arcade game. The game has two playing modes: Modern and Classic. Modern features better graphics and some extra features.

Move your base at the bottom of the screen and kill as many aliens as possible. Aliens will move across the screen in a formation of 10 x 5 and for each switch of direction the will close in a bit on the player. The more aliens the player kills the faster the remaining aliens will move. Now and then a mothership will appear at the top och the game area. Destroying it will give the player some extra points, in modern mode destroying a mother ship will on later levels reward the player with better defences and fast shooting missiles.

The game was written in assembler.
