We currently have a project requiring common (WHITE) Human Bridge Officer (BOFF) candidates. If I remember correctly, we'll soon need some of other species too.
Now... is there a way to obtain them without purchasing them via the Exchange? (All the BOFF candidates I keep earning via assignments are always blue and purple, so the project won't accept them.) Currently, the Exchange price for one is 175K EC, which is way too much considering we need 30 BOFFs for the current project and more to come.
