I've got some ideas on how I want to work Armada and Legion together, but I want to ask what other people would want.
Currently I'm working on Special Ops that allows a squad to infiltrate enemy planets and do nefarious things, like assassination or sabotage.
I plan on doing joint Armada/Legion sieges of planets, boarding vessels that result in a Legion battle, planetary and ground defenses, strategic bonuses for planets, and some other fun stuff. This will be added onto the Armada campaign rules that are currently being tested.

Tell me your ideas. What do you want to see?
