I would be interested in a comprehensive explanation of when certain actions are turn ending. There's those where it's simple, like shooting, as they say "will end turn". Others which are obviously are not turn ending, but consume an action, like a single move, or reload. And of course free actions like opening doors that are neither turn-ending nor cost any actions.
But then there seem to be some actions, like Torque's "Tongue Pull", and Axiom's "Psych Up", which seem to be either free actions, or automatically non-turn-ending - at least I've seen gameplay of Axiom moving, using "Psych Up", and then attacking.
Is it that they are just free actions, so you could psych up and then double-move? Or do they grant an additional action if used as the second one, so move-psychup-move would be better action economy?
I've also been looking for a mod akin to XCOM2 to display action costs, but haven't found anything so far, surprisingly.
