Membranes atm suck, they have essentially no purpose, give marines sight, and are basically trolling.
What if we do the following:
Make membranes stronger than walls, at the tradeoff that this thick, horrible membrane is see-through which provides a tangible tradeoff to do so.
You could make membranes stronger against a particular kind of damage like machetes, making it hard to cut or something, or stronger in that they’re more explosive resistant? just generally more hp?
it feels like a reasonable tradeoff, giving marines sight (the most valuable commodity) in exchange for being harder to remove
you could also make membrane require supporting walls to be held up, like horrible impassible shit kinda strung between them but can be seen through (would require a resprite)
alternatively remove sticky resin and have membranes be a psuedo pass-through resin that is supported by nearby walls ala the movies of this horrible vertical lines between objects
or membranes not allowing light to pass through them so only really useful for xenos and humans with nvgs
