Atari 2600
Threshold
You are patrolling an unknown sector of the galaxy, armed only with your ship's phaser and your skill as a flyer when suddenly you are fired upon by unidentified alien attackers. Quickly you maneuver to avoid their missiles as you return their fire. You fight them off, six against one, to find they were only the vanguard. Wave after wave of aliens attack, each more threatening than the first.
