Intruders

## Description

_Space Intruders_ is a clone of the popular arcade game _Space Invaders_ for
the BBC Micro, where the object is to navigate your ship left or right, using
its built-in laser fire to destroy five rows of aliens who work their way down
towards you. If any of these aliens make contact with the ship, a life will be
lost. Four bases are there to protect your ship, but these bases can be
destroyed piece by piece. From time to time, a UFO will make its way across
the screen; and shooting it will award you with bonus points. The game ends
when all lives have been lost.
