Brickset has revealed two new polybags for LEGO Galaxy Squad: the Mini Mech (30230) and the Space Insectoid (30231). The instructions are readily available via Brickset’s instruction page. The human minifigures are ok but I would rather have more alien minifigures. These polybags are expected to be released sometime in 2013.
