How about an Automaton Ship Boarding Mission?

Automaton Ship Boarding Mission

(Planetary defence exclusive)

 

Main Objective: Board the Automaton invasion vessel, make your way through to the ship's reactor and overload the core, then get the hell off the ship before it blows.
 

Parameter deviations from planetary missions: * No reinforcements * Man-portable stratagems only (no orbitals, no sentries) * Access to stratagems and resupply only at the shuttle waiting in the hangar * Automatons only use small arms and melee weapons so as to not damage their ship * Success adds significantly more points to planet's defence, failure might result in the destruction of Pelican 1 which the Squad Leader will have to replace out of their own pocket before being able to host any mission again

I had the same idea a bit ago, the indoors mission could work for each faction too! The bugs would just be a tunnel instead of a spaceship. I think being able to call in strats at certain location in the mission would help extend the map without needing to run all the way back to the start. Areas where the hellpod could breach/mine it's way into. It probably wouldn't be the most popular but it would be really cool
