For C3/C3+DS. Power-Ups are little items that only your Ettins can carry about. When they are carried to their respectful place, a shee ark item-recycler,theagent maker(or whatever it is :P), or the blueprint colector will gain some power to make/collect/destroy agents. If there is enough or more then enough power then it will perform what it's made to do. If there not enough to do what it needs to do, it will stop and force you to help the ettins get the power-ups to their respectful place. As I(robertbrockuscpp) don't have C3 I can't grab an image for this page. There should be enough infromation on there to help you get the idea anyway. Not to be confused with blueprints.
