Annihilator
Annihilator is a Galaxian variant written in 68000 assembler.
Your ship is at the bottom of the screen and you control it with the joystick.
The aim of the game is to destroy as many aliens as possible before you lose
your only ship. On every level a large group of aliens comes down from the top
of the screen to the middle of the screen and you have to move left and right
to avoid them and fire your ships weapon to destroy them.
At given intervals aliens will break formation and fly down the screen against
you. When they reach the bottom of the screen they will reappear at the top.
Some aliens can be destroyed with only one shot while others can take several
rounds before they are destroyed. As you progress in the game the aliens will
move faster and in larger number. Some aliens will leave power-ups after being
destroyed. These power-ups can give extra energy or time limited shields.
