You’re the last defender of the Earth and must fend off waves of alien invaders – no pressure, right?
Shoot laser beams to take out the alien ships, but they get faster the closer they get!
Move your space ship side-to-side to avoid enemy attacks, or you can hide behind the barriers to miss enemy fire – you only have three lives so make them count.
Prevent the aliens and UFOs from descending to Earth and get a massive score in this arcade classic.
