Subterrain

A Claustrophobic Descent into Survival and Sanity
At first glance, Subterrain might appear to be just another sci-fi survival game, but it quietly grows into something far more compelling—an oppressive, slow-burning descent into isolation, systems management, and dread. Set in the crumbling underground colony of Mars, the game throws you into the role of Dr. West, a wrongly imprisoned scientist who wakes up to a facility gone silent and a red planet no longer under control. What follows is a harrowing journey through survival mechanics, strategic exploration, and mounting psychological pressure.
The Depth Beneath the Surface
What truly sets Subterrain apart is its refusal to hold your hand. There's a rough charm in how it throws you into a cold, uncaring world with no tutorial parade. Instead, you're left to figure things out—how to manage oxygen, power, water, hunger, thirst, infection, sleep, mental stability, and even body temperature. It can feel like spinning plates on a unicycle, but the satisfaction of mastering this brutal rhythm is what gives the game its hook.
There’s a constant need to balance scavenging expeditions with life support systems. The colony is slowly decaying—power runs out sector by sector, oxygen systems fail, the infection spreads—and there’s no stopping the clock. That time pressure turns every decision into a gamble. Stay out too long and you risk exposure; go back too early and you waste precious time and resources.
The game’s semi-procedural map layout and interconnected sectors add a sense of scale and realism. You're not just exploring for loot—you're piecing together the story of a disaster, one crumpled note and shattered corridor at a time. Combine that with an eerie, minimal soundtrack and subtle environmental storytelling, and you’re left with a creeping paranoia that never fully fades.
Not Without Its Scars
For all its ambition, Subterrain stumbles in ways that can test patience. The user interface is clunky and often feels like it's fighting against you. Managing your inventory, crafting, recycling, and researching takes up a huge chunk of time—and not in a rewarding way. It’s hard to shake the feeling that some of the systems could be streamlined without losing the challenge.
Combat is another rough edge. While it's serviceable, it lacks finesse. Gunplay feels floaty, and enemy AI often behaves more like a nuisance than a true threat. Boss fights are underwhelming, occasionally reduced to frustrating bullet sponges rather than climactic encounters. The visuals also won't win any awards, with dated character sprites and environments that start to blur together over long sessions.
Then there's the pacing. The early hours are brutally slow, and some might check out before the systems start to click. It's a game that demands time and attention, and in return, it gives anxiety, repetition, and a sense of being constantly behind the curve.
Pros:
Deep survival mechanics that reward strategic thinking
Atmospheric world design and immersive environmental storytelling
A strong sense of tension and progression over time
Uncompromising and unique gameplay loop
Cons:
Clunky interface and overwhelming micro-management
Underdeveloped combat mechanics
Repetitive environments and dated visuals
Slow, sometimes punishing early-game pacing
Final Verdict
Subterrain isn’t polished or easy to love. It’s the kind of game that tests your resolve as much as your skill. But those who stick with it often find themselves hooked on its relentless systems and the raw satisfaction of surviving against mounting odds. It's messy, it's tense, and it’s undeniably one-of-a-kind.
Score: 7.5/10 – A flawed but fascinating gem buried beneath the Martian soil.

Loved the opening hours but eventually hit a wall where progression stopped being fun and became more tedious.
There is an absolute gem of a game here hidden under a few poor design decisions. I recommend heeding the warning of the negative reviews that detail this.
Yet, still I recommend giving it a try. The atmosphere and overall gameplay loop for those first few hours is just so darn appealing it's worth seeing if the entire game is for you.

I wanted to play this game before playing Mines of Titan because I wanted to get all the backstory. I feel like playing definitely gave me some backstory though it doesn't really feel like a lot of it gets explained until the end. Until then you do get some important backstory and a lot of notes about randos doing stuff around the facility.

One thing I don't get is why this Mars base has so many pool tables and slot machines. Even outside the casino. Which...why is there a casino?

I do like the combat to a degree. It feels like there's a lot of ways to go about it, but I stuck to a pistol/shotgun combo which worked pretty well.

Tech progression felt okay I suppose. The 2nd tier facilities have 10 floors and I feel like it's only like that to fuel both the length of the game and to provide more materials for crafting. Sometimes it just felt like a slog because of it.

Largely I do like the game. However...the last boss. I literally just gave up. After the 10th shot, I just gave up on that route. The dev does recognize the pillars had too high a health and did bring it down, but there's just so many and by the time I got there, I couldn't get any more mutant-related materials so making the drugs to keep myself moving was just out of the question.

If I could use an item and it would still get used even if you got hit then I could probably do it, but there's just too much going on.

Did I originally get what I set out to do from playing this game? Yes. Do I kind of wish I watched a video about the history (if anyone really ever made one)? Also yes. Still going to recommend the game though because I'm sure someone who is more into bullet hell games would love that part.

Can't ever imagine beating this on perma death, but I had fun. Pretty repetitive, but I liked the game loop.

Very challenging and addicting. Top down is not something I usually like, but this has me consumed.

Well, well, well. This game caught me completely off guard while I was just going through my games library, testing one game after another. It hooked me in and I had a great time exploring, crafting, beating mutants, and leveling. The story was also really nice for such a little gem. Once you understand the crafting and researching mechanics this game will really grow on you.

Enjoyable survival game - top down view gives it a different feel - like playing GTA 1 & 2, but with monsters chasing you, and very little light.
