Into the Slimy Mines is bringing a mix of a roguelike tower defense game with a card-driven twist that’s coming to Steam Deck, Linux, and Windows. Thanks to the creative team at Ant Workshop Ltd, for this slimy adventure. Making its way onto Steam soon.
Into the Slimy Mines looks like the kind of game that starts simple, then quietly eats your whole evening. You are stranded on a slime-filled moon, your Dwarven crew is missing, and every tunnel you dig might save a friend or open the front door for a swarm.
That is the hook. That is the danger. And honestly, that is exactly the kind of messy tactical pressure I want on Steam Deck.
A slime moon, a lost crew, and one very bad day
Into the Slimy Mines launches on May 29, 2026, coming to Steam Deck Verified and Linux PC via Proton. As outlined by Ant Workshop.
We’re not currently planning a Linux-native version of the game, but it is Steam Deck verified and works well through Proton
So, at its core, this is a roguelike tower defense with a card-driven twist. You build a deck, carve paths through the ground, and place defenses right where the slimes are going to crawl through.
That sounds good on paper. In play, I can already feel the panic.
Since every Dig card is a choice. You are not just opening a tunnel, but you are creating the road your enemies will use to reach your rig. You will need that path to rescue your missing crew, but you also know the swarm is going to use it against you.
That is the good stuff.
Dig Into the Slimy Mines first, regret later
The game sends you into 30 dig sites across 6 unique biomes, with 5 increasingly difficult depths in each one. So this is not just a quick little slime stomp. There is a full rescue mission here, with real structure and plenty of room for bad decisions.
You drag Dig cards to excavate tunnels toward your trapped crewmates. But the second you open that route, the slimes get ideas.
I like that kind of pressure in strategy games. It makes the map feel alive. You are not just reacting to lanes. You are building them yourself, then praying your defense plan does not fall apart.
Pick your Guild and build your problem-solving machine
Before each descent, you choose from 3 unique Guilds: ANVIL, WARHAMMER, and PICKAXE.
That alone gives Into the Slimy Mines some nice replay energy. Different guilds mean different ways to handle the same chaos. Maybe you lean into brute force and build smarter. And maybe you do what I usually do and create something brilliant that collapses five minutes later.
You also get 6 upgradable Drill Rigs, with up to 30 different add-ons to match your play style and deal with each location’s hazards.
That matters for Linux and Steam Deck players too. This sounds like the sort of release that fits handheld sessions perfectly. Quick decisions. Clear tactical pressure. Lots of build variety. Big “I can squeeze in one more run” energy.
Into the Slimy Mines – Release Date Trailer
The deck is where the trouble starts
Into the Slimy Mines is not only about turrets. The card system gives every move weight.
You can dig, defend, and you can upgrade. Since you can patch things mid-wave when the whole plan starts making scary noises.
There are 10 Buildings and 26 turrets, each with 3 upgrade levels. Upgrading is simple too. Place another copy of the same card on top of an existing one. A Level 1 Cannon plus a Level 1 Cannon becomes a Level 2 Cannon.
The maths checks out. The slimes probably hate it.
There are also 15 Gadget cards for those panic moments. These can slow or blast groups of slimes and repair your buildings mid-wave. So when everything goes sideways, and it will, you still have a chance to claw things back.
More than just Into the Slimy Mines splatter
The gameplay also digs into the story. Literally.
You are rescuing the Dwarven crew of Captain Firebeard, and there are up to 20 datapads to collect along the way. There is also the ship AI, F.O.R.G.E, which already sounds like the type of character I will either trust completely or blame for every disaster.
That extra lore layer is important. A tower defense can live on mechanics alone, sure. But give me a weird moon, a stranded crew, a grumpy space-dwarf vibe, and a slime infestation, and now I care about the run.
Now I am not just protecting a rig.
I am getting my crew home.
Built for repeat runs
Of course, Into the Slimy Mines has meta progression too. There are 17 Meta upgrades to unlock and improve, making each descent a little more manageable as you keep pushing deeper.
That is the sweet spot for roguelike design. You fail, but you bring something back. You learn the map, the cards, and which turret setup works. And also, which one turns your base into slime food.
And with ore to unearth for bursts of money, lures to distract enemies, generators to keep the rig running, blockades to slow the swarm, and displacers to mess with enemy movement, the game looks like it wants you to experiment.
Not politely.
Aggressively.
A strong fit for Linux gaming
Into the Slimy Mines roguelike tower defense game with a card-driven twist has the right pitch for players who like systems that click together. It has deck-building, tower defense, upgrades, meta progression, rescue goals, and a big pile of slimes trying to ruin your day.
For Linux players, the big detail is clear: Into the Slimy Mines is coming to Steam Deck Verified and Linux PC via Windows PC through Steam on May 29, 2026.
