well, BHG Core, Order and Zoners all have a common enemy- the aliens. so, why not add alien hunting missions? - lesser money, but more remains . will increase activity, especially in Delta. Discuss away.
plus, not necessary for remains to drop. but it would atleast give the guys a purpose:for the order- less noms left , for the BHG - more research subjects on how noms die
As one who likes to play mostly in the Omicrons, this would be quite fun and also a passtime, when there is no one around. Increase in activity too, if at all it happens.
