The superb Colony 87 is back, with another glorious half dozen sci fi civilian characters.
I think the adviser (the guy in green) is the pick of the bunch for me, whispering sycophantic morsels in Governor Karthur's ear. The two mechanic types will be useful in a lot of scenarios too.
If you want them, you'll have to hurry: sixteen hours to go at the time of writing. The original Colony 87 set is available too, if you missed them the first time.
