Review for LEGO set 70700 Space Swarmer from Brickipedia
“The set is mainly focused on the "Space Swarmer" taking on a Blue Team Galaxy Squad robot, who is armed with a large blaster, using a camera piece with two red studs on one side, two connector pegs with nobs on both sides of the gun, which support 2-stud long TECHNIC beam,... More as the end of the gun. The robot also has a jet-pack, made with two space guns, which originated in Alien Conquest. The back of the jet-pack is where an antenna is positioned.”
