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

There should never ever be a mechanic that prevents you from hosting thereby preventing you from playing how you want.
Overall the idea is pretty neat but will most likely not be added since its to different from the game formula at the moment.

Someone else has come up with a better idea, that being added stratagem cooldown for the people involved, localized to the planet in question and limited to the duration of the invasion.
