This could be when you are scavengers,
There could be a new unit... or can just use the basic unit to build structures.
If i remember correctly, on the PS1 version when i played as the scavengers - I could make their units but i cannot on this version. Could this be fixed?
In this game mode, you can research only to a certain extent, but if you had an ally, E.G The new paradigm. They could transfer technology in a sector for your scavengers to equip their vehicles. Or minus that bit and fight against the ever-growing "project"
Or for modders - Make a scavenger sided campaign like.. "how it started" with them.
Might add more to this, please give your own ideas and/or add to it in the comments.
