Nice. Super keen for the expansion. I'd assume tungsten mining drills, lava resource extractors and gas pumpjacks will be the major new buildings for this planet. Tungsten will probably be used in advanced buildings (high heat tolerance- lava landfill, rocket engines) and armour equipment as well as science. It seems that tungsten extraction may attract lava biters? The new terrain also looks great and it definitely seems like they're holding up the promise of delivering a whole new game's worth of content with this DLC.
It reminds me a lot of Mindustry's Erekir, both in setting and in some gameplay implications (tungsten deposits, lava as a resource, heat changing gameplay solutions).
Oh my word. Please tell me we can concrete over that lava, otherwise I am going to fall into it so often it will be almost, but not quite, very funny. (Because my driving totally sucks in this game).
