Space Invaders (PS1)
The Playstation version used the basic concept of the original game, but instead of ending only when the player lost to the aliens, it was possible to win the game. The player fights over the planets of the solar system fighting off 10 waves of aliens before fighting a boss. Upon defeat of the boss, the moved on to the next planet.
Normal had the player go though 8 planets, while expert tweaked the difficulty as well as made the player go through Mercury and Alien World upon completion of the normal 8.
