Picked this up to add some options for a Solar Blades and Cosmic Spells project in an alternate setting, and this supplement is a great addition to what is in the core game. In a really smart move, the androids are done as an archetype rather than an alien species, which gives more room for custom abilities. "Species" are still an option for your android, but as types of androids (basically warbot, hazardous environment bot, construction bot, and a high skills bot). Lots of gear options too, for the android and for those living and working with androids.
