I was wondering if it would be intresting to play survival/scavanger type campaign, no money, no stations, everything is crafted and upgraded with resources, you could explore ruined stations, subs for resources, finding new submarines in hidden outpost or abandoned colonies. You could also find other survivors hiding in those abandoned structures and recruite them. I think it would make the game more tence on the resource standpoint and potentially more story driven. I have a very crude story togo on. So basically there were colonies beyond the ridge that were destroyed by radiation and your sub with minimal resources and box of antirad was tasked to figure out what happened, there were more and better subs sent before you, but didn't come back, do you aren't expected to survive. The map is 3 zones: the border, clear sky and precurser city. The border is where most population lived full of human ruins, radiation pockets snd even hiding pirates. Clear sky is zone where the ice of europa has melted into a sea and is leaking lots of radiation into the ocean, you also can see moons surface and explore outposts made by cutoff coalition scientists (they dead). The radiation in this zone is extreme, and monster are more dangerous. In order to stop what's happening you need to go deep into alien city. Full of alien ruins and huge city protectors as abyss creatures , it's extremely dangerous with gravity traps and sonic waves that disrupt submarine radar and movement. Reaching the end you could have a choice to stop what is happening or not.
