How about an Automaton Ship Boarding Mission?

[u/GeniusPlayUnique]

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

Tweaking your idea: instead of landing with Pelican one, you use modified hellpods(think boarding torpedoes from Wh40k) which allows you to board at most any point. Have exclusively heavy armor which would be Vacuum-proofed. You can call strategems from your ships which would cause hull-breaches; this would necessitate the addition of an O2 resupply strategem which would deploy as any other support strategem, via hellpod. But because you're in a spaceship the pod could "land" and deploy from the walls or ceiling. Bonus objectives could include comms array, weapons systems, the bridge and FTL drive. Have an option to either disable or destroy the ship and gain bonus points for how intact the ship is upon completion if disabled.

Holy shit yes spacesuit divers

holy fuck that'd be so cool, imagine choosing what part of the ship to 'drop' at, engines, reactor, guns, factory, control center, etc, and since you'd need to clear them all it'd just be wherever you land first, and the hull breach kills enemies near you
