Moonbreaker is an early access turn-based tabletop game by the Subnautica devs, and before you ask, no there isn't a Blue Eyes White Basking Shark piece that inhales everything on the board. There are, however, plenty of sci-fi people who wield spears and guns and do battle by spending a currency called Cinder, if that's your jam.
Whether you're new to tabletop strategy or already like bashing miniatures together, the game makes for a perfectly enjoyable time. I just don't know whether it goes beyond "perfectly enjoyable" into "thrilling", though, and that may be down to its lack of, well, lots of things. Give it time and it may just evolve into a game of serious depth but right now it's a bit too miniature to recommend wholeheartedly.
