Maybe we could have terror missions where we go and defend government bases (looks like x-com bases aesthetically using the same basic blocks except for hangars so once you enter in an elevator, there is no way out unless you have jetpacks or beat the level) and there are security guards with pistols and rifles (work like civilians as in not under your control and their guns are cheaper than yours so they sell for less and maybe even have an alternate skin?) and maybe 1/2 HWP's and you have to make sure that they don't destroy some sort of control center (mission doesn't fail if you kill all aliens just a large subtraction from score/rating) anyone think this would be interesting? (needs fine tuning though probably)
