“Pixellore sets the scene well, and immediately hooked me with its foreboding and mysterious opening.”
Preview – Indie Game Magazine

“Even though Subterrain is still early access, the developers have done an amazing job. Unlike many Indie games this one already feels finished. There is always room for improvement, but the game has what it takes to become one of the better Indie survival horror games that are out there. If you’re a horror survival fan, this game needs to have a spot in your collection.”

By 2050, humanity has finally colonized Mars thanks to the efforts of one man, Jeff Murray. To avoid Mars’ high radiation levels and inhospitable temperature changes, he built a city underground. This city was named Mars MPO. Free of the constraints that often plagued businesses and researchers on Earth, scientists and entrepreneurs flocked to MPO.

Recently, Dr. Albert West has migrated to MPO at the personal invitation of Mr. Murray. West has been working on a cure for Alzheimer's disease in a race to save his wife, Jennifer, from dementia. His efforts are cut short; a lab accident leads to an accusation of murder and a prompt prison sentence.

We join Dr. West a little over a year into his prison sentence. It’s been a week since the guards mysteriously vanished. Dr. West is about to find out why.

Power cell depleted, firearms and flashlight non-functional, only weapon left is a wrench that's about to break. Down to 20% of my oxygen supply, tram station is three pitch-black, freezing, airless floors above me. I can hear a crowd of those things shrieking and clawing at the door to the closet I took cover in. I've been awake for almost 24 hours and can barely run.

Found one grenade in a drawer, and I have less than two hours to get back to Central before the generator overheats and I'm stuck here forever.

On top of it all, I seriously have to poop.

After reading many many pages of size 8 font to jump over a high learning curve, the player will have fun for a few hours, before coming to understand the game essentially never changes from the grind you started with.

Purchased the game thinking it looked very good, loved the premise of the game and the survival concept. Unfortunately when running the game the tutorial screen cannot be closed rendering the game unplayable unless you skip the tutorial... not great in a game where not knowing what you are doing will result in death!

Tried in both full screen and boarderless window and get the same issue. Terribly unfortunate as the game seems very interesting.

Fantastic game, it has survival, crafting, base managment and long play length (no where near finishing after 30 hours), well worth it.

10/10, Would be eaten by mars mutants again.

Long tedious grind so you can do a boss fight that goes on so long your character can die of thirst.

Your choice of 4 annoying weapons: the slowest pistol in the universe, a submachine gun who's shots travel about 15', a shotgun that's utterly useless unless you have it jammed in your target's mouth, and a bomb shooter that gets so hot after one shot you automatically drop it. Upgrades to these weapons consist of trivially small changes in both the image of the weapon and it's stats.

Spend hours slogging through nearly identical levels gathering what may as well all be called 'junk' cuz it just goes into a recycler anyway, so you can spend hours waiting on research and building to be done, so you can go out and get more junk just so you get slightly better annoying weapons, repeat.

The game could have a lot more depth, but it's just not there.

I found the game extremely tedious. It definitely kept me busy, and for that it gets kudos, but it was the busy of "Oh gawd. I have to go back there again? Oh jeez. I have to do that again? I have to wait how long for this to build? I missed one item because of a 3 pixel difference in the tiny picture, and now I have to spend 12 hours catching up? Ug.

So, if you're a masochist, this game is for you!

I own over 1000 game. I have so many because I want to find the the rare gems that immerse me in a new gaming world. This game looks a little Fallout 1/2ish though its graphics are more modern. The gameplay is all about surviving in a bace on mars dealing with the needs of your characther along the way whilst staving off an enemy horde. It sounds simple but the devs design is what makes it special.

Amazing! I totally love this game!

The only con is the monster differentiation. Hope to see more monsters soon!!

I had great time with the game but prepare yourself for a lot of grind and rince and repeat to beat it. Knowing how things work would probably made it less of a grindfest I went through.

Subterrain is exactly what indie gaming should be about—on the surface a simple but rewarding little game that hides unexpected and well-implemented intricacies.

Fundamentally, the gameplay clearly builds on Team 17's highly successful Alien Breed series from the early nineties (resurrected in 2010.) However, in terms of enemy difficulty and numbers, it hearkens more to forebears like System Shock. (It also inherits some of the latter's fraught, climactic atmosphere.) While you will sometimes (as infestation levels get higher) get swamped by clusters of enemies, Subterrain favours more careful and tactical progress than Alien Breed's spray-and-pray bullet-bonanza. Also, once you get through the tutorial level, Subterrain is entirely open. You choose where to go and when to do it, which—together with hints found in various notes and messages around the base and the rare comment by Dr. West himself—helps to add much-needed context in lieu of other narrative elements.

The game isn't perfect. There are things that don't seem to entirely add up. For one, the guns—despite being brand spanking new out of the almighty 3D printer—are ridiculously shoddy and require constant repairs. While this is obviously done to match up the various attrition factors during a mission (meaning you never know which one is going to force you to retreat back to base camp to lick your figurative and/or literal wounds) it feels like an unwelcome amount of hassle, and makes little contextual sense.

Also, while most game aspects are explained in the tutorial, there are still things you will need to figure out for yourself, and some of them aren't entirely obvious. Because the game has a lot more elements to keep track of than your average top-down tactical shooter, it's easy to miss or forget one or two popups—especially since the dialogue font does not track well at all. (Luckily, you can easily access help sections from the Escape menu.)

The crafting system is lovely from a mechanics perspective, but its progression is ultimately way too formulaic. It would have been much more thrilling to find the occasional half-functioning gun by a dead guard and research that, rather than just shoving the most recent iteration into the research machine and telling it to come up with a slightly better one.

None of this, however, draws much away from the fact that Subterrain plays very well once you get into it. It is consistently tense and atmospheric, and the difficulty scales brilliantly as the infection spreads and the monstrosities mutate into bigger, badder... well... monstrosities!

Visuals are very nice and good-looking for what they are. Although this is a top-down retro-pixellated game, it is clear that it's the bespoke variety rather than the "couldn't be bothered with proper graphics" one. Everything looks right and fits together smoothly. It really looks like an updated version of Amiga graphics, which is a nice touch for those of us who remember that far back.

The music is apt, well-made and atmospheric, if a bit too uneventful. (It could definitely have done with a few string swells and such.) Game sounds are fairly good in general, although the audio implementation is rather simple (occasionally even haphazard) and sounds do get a bit repetitive. This is—retro shimmer aside—2016, after all. We do have rather higher expectations, these days.

All in all, Subterrain is a keeper. If you're into this type of gameplay, it offers hours upon hours of taut, focussed fun with enough variation to make up for the lack of narrative—and that at a reasonable price. (Presently 16,99€.) Highly recommended!

I originally thumbs-down'd this game as I experienced a bugthat causes you to be unable to exit the tutorial menu for certain people. Which meant I wasn't even able to leave the starting area.

However, the developer has fixed the problem and I've been able to play. The game has a nice atmosphere, and the more open style of game play is great for people who don't like being on a set track.

For now, I can't recomment. Will update as I play more.

First experience with the game:

Doing tutorial, get to equipment/ bag (tutorial messages if enabled on creation of a new game pop up automaticaly) screen, the tutorial tabs work, and the close button makes a sound... But the screen never closes. I Click out of the game to force close, the pause menu pops up (on easy to learn the game). I exit to main menu, probably having lost all progress so far... The stupid tutorial screen is STILL in the middle of the menu, until I try close again.

Hopefully the rest of this game isn't as buggy.

First edit: Just know all the positive reviews, or most of them, are given in humor, and add nothing to what makes the game good or bad. Read the reviews with caution, and know full well a LOT of them would be not recommended, but then no one would consider these people funny and they would be starved for attention. The game is nothing but a grind, and gets dull fast, but starts off really strong/ promising.

Will continue adding edits/ updates to my personal experience. So far, can NOT recommend since a game breaking bug ruined my first impressions almost immediately.

Subterrain starts promising, but it gets real dull real fast. The game world is littered with food items and crafting ingredients, turning the survival gameplay into obnoxious inventory management. The oxygen and thermal canisters add nothing but an annoying ticking clock to your exploration, necessitating that you either clog your inventory with canisters upon canisters or backtrack all the way home every 20 minutes. The research system is just a glorified upgrade booth where every new piece of tech is exactly the same as the previous one except with slightly bigger numbers. The ability to "Customize your ranged weapons using modular parts!" is just a big, fat, stinking lie, because the only difference between one heatsink and another is that one is strictly better.

Combat is monotonous, offering only a handful of distinct varieties of enemy and three kinds of guns with which to kill them. On top of that, even the useless starting enemies that could barely kill you if you let them can take several seconds of sustained fire to bring down, making most fights more of a chore than a threat. And when something interesting does happen, the uninspired audio/visual design and murky UI conspire to make it feel more like a momentary annoyance than a tense life-or-death situation. I played with permadeath on, and I still couldn't even be bothered to get upset when I was beaten to death by super mutants because it just felt so anticlimactic.

Perhaps all of that could have been forgiven if there was some meaty lore to dig into, but unfortunately the story is unimaginative, the characters are uninteresting and the writing is mediocre at best.

In the end, Subterrain feels nothing so much as unfinished, like it's still in the late stages of early access. It's functional, but lacks the finishing touches that would have made it great as opposed to (barely) palatable. 5/10, play NEO Scavenger instead.
