A quick notification for those who haven't checked the annoucement of the new version of the Nomads faction : there is a new feature in it that allows to build pre-upgraded SCU. It is available by default for the Nomad faction, but you can also have it for the other factions by activating a mod that is built in the Nomads version. Of course, you don't have to play with the Nomad faction to try it.
Having pre-upgraded SCU allows you to know better what total cost you will have for your Super UEF shielded SCU of Doom, or your Seton Knightmare Teleport Sera SCU. It makes it also much easier to plan your SCU use, and ease their management a lot, removing, if you want a specific SCU, a lot of micro.
Give it a try!
