Galaga --» Pew --» Pew

This LEGO set is comprised of all 10 characters from the Galaga arcade game along with a commemorative tile with the Galaga logo.  The design was goal was to ensure that each character, when compared to the original 16x16 pixel sprite, would be immediately recognizable and a near pixel perfect representation of their lower resolution counterparts.

FIGHTER

You control a spaceship which can move horizontally and fires a pair of missiles.

BEE * BUTTERFLY * GALAGA BOSS

The 3 main enemies have animated sprites which have both an open and a closed state.  For these characters, the LEGO builds have articulation to allow them to represent both states.  This was a massive challenge for the Galaga Boss as the overall volume changes between the opened and closed states.

SCORPION * BOSCONIAN * GALAXIAN

When you advance in the game, you reach stages where one of the Bees or Butterflies will transform into a set of 3 other characters which immediately dive towards you.  Two of these sprites were borrowed from the Galaxian prequel.

DRAGONFLY * SATELLITE * ENTERPRISE

The Challenging Stages introduce new character sprites. On these stages you have one opportunity to shoot each sprite while waves of them come in and out of the screen.
