Space Invaders is an implementation of the classic arcade game. The game has 2 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 they will get down and get closer to the player ship. The more aliens the player kills the faster the remaining aliens will move. You have 4 shields to protect you but they desintegrate slowly because of the aliens bullets. Randomly, a mothership will appear at the top of the game area. Destroying it will give the player some extra points, in modern mode destroying a mother ship will reward the player with better defences and fast shooting missiles. The game was written in assembler.
