A turn-based sci-fi survival horror with rpg character advancement, a story compelling enough to hold interest and a unique setting with a hefty dose of survival-craft style resource collection and management. Subterrain: Mines of Titan won't be to everyone's tastes, but if anything it offers seems appealing give it a chance and you will probably find yourself pleasantly surprised.

The game also lets you tweak almost every aspect of it's mechanics and difficulty, both at the start and during play as well. No need to worry about having to restart to tweak/disable something you don't like (this is something I feel should become the norm in every game, let people play the way they want.).

The combat and exploration is solid and quite fun, giving you a choice of several different weapon types to choose from each with their own related perks/abilties and making each feel quite different in how you approach combat. You can equip two weapons and swap between them with the press of a button (swapping takes a single turn) with some weapon types having perks that specifically compliment hybrid-style builds (pistols being one).
Combat can be quite dangerous with injuries and negative effects being outright death sentences if you are reckless and under-prepared.

There is also a "doomsday clock" constantly ticking away every single turn (NOTE: If you hate that type of thing, it's not as bad as it sounds. I'll say more in the next section). You are given a few ways to slow its progression, but you can never stop it. This adds a good balance of risk/reward when choosing whether to push forward or return to camp and consolidate your gains to try and give yourself a better advantage on the next trip.

The ticking clock can be tied to progression (in fact that is it's default when starting a new game) instead of time, or outright disabled. I started my first run with the default and then decided to give the time-based one a try after I understood how the mechanic works. It really isn't that oppressive, it affects enemy evolution, strength, and density rather than a "You Lose" timer. I still had plenty of time to putz around and take my time, it acts more like a subtle pressure to keep you from trying to power-game by repeatedly grinding earlier areas.

The crafting/research/resource gathering is far less grindy than it first appears. You find stuff in the mines and haul it back up with you to be researched/scrapped/crafted by the other camp members while you are down below dealing with the underground horrors. To that end you can queue everything up from anywhere -- which means you don't have to worry about forgetting to queue something up and wasting time. No need to wait around for your gear to be crafted before heading back down, you can bring up a load of stuff, have it researched, disassembled and crafted into a new set of gear/supplies that will be waiting for you the next time you come up to drop off your spoils.

The camp management is pretty lacklustre, honestly. I left it at default and I don't think there was ever a time where I thought about it as anything other than a way to turn my excess materials into credits. The same can be said for the occasional invasions that happen back at camp, if you keep your turrets upgraded and replace barricades you never even have to think about them, I played with them on, but next time I play I will most likely disable them as they really didn't add much to the experience for me once I hit the half-way point.

The story and characters are well written, each NPC has at least one side-quest that will eventually pop-up that will let you get know them a bit better as well as provide some hefty exp and income. I also enjoyed that the story hinged more on a group of rag-tag professionals each banding together to support one another in their own way, however small that may be. I found it quite refreshing compared to the usual trope of "everyone is a different shade of ♥♥♥♥♥♥ or depressing because our situation is dire" that is so common with these types of story. That being said, I would have liked a bit more interaction with them in some way, other than just their related quests. It does work with the narrative though as your character is to pressed dealing with the underground horrors and trying to keep everyone alive. Which makes the brief interludes of helping people around camp feel more impactful.

Overall, its a fun game that I'm glad I decided to play. Give it a try if anything here seems appealing to you. I consider this money well spent and I look forward to seeing more from this Dev.
