Combat platforms
Combat platforms can be constructed in Engineering once the required research project has been completed. Once constructed they can be used in place of regular xenonauts. Combat platforms use their own loadout separate from human xenonauts. Their armor is upgraded automatically.

Combat platforms are robotic units so they are immune to stun damage, gas damage and morale effects but vulnerable to EMP damage.
