The full Galaxy Squad line has been revealed over on Brickset. We get 6 sets: 4 "good guy" sets, and 2 "bad guy" sets.
There are tons of new pieces in these sets. Not only new minifigure gear, but also plenty of new pieces that will make for some great MOCs.
70700 Space Swarmer. 86 pieces. Ages 7-14.
Check out the rest of the line below.
70701 Swarm Interceptor. Ages 7-14.
70702 Warp Stinger. Ages 8-14.
70705 Bug Obliterator. 711 pieces. Ages 8-14.
Pretty cool, huh? Hopefully this theme will turn out better than earlier space themes.
