Castle Away is bringing its fast, addictive roguelite autobattle castle builder game to Linux PC, Mac, and Windows. All of this comes together thanks to the creative drive of developers René Slump, Sim Kaart, and Matthijs Koster. Which is due to find its way onto Steam.
The first time I loaded into Castle Away, I didn’t expect it to get my attention. But a few minutes in, I was already leaning forward, trying to get one more perfect build out of a tiny grid while chaos crept closer. Now the new update just released, and honestly, it feels like the moment this game opens its doors to way more of us.
Castle Away finally feels like everyone’s invited
So here’s the big one. Castle Away is no longer just a Windows thing. Native support for Linux and Mac is here, and it runs clean. No weird workarounds, no hoops. Just install and go.
If you’ve ever been the one in your group stuck watching others play because your setup didn’t match, that changes now. This native playtest actually feels like it respects how people play. Whether you’re on a PC you’ve tuned for performance or setup you use for everything, you’re in.
And yeah, controller support is live too. I tried it kicked back with a controller, and it works way better than I expected. The UI feels built for it, not patched in. It’s the kind of thing that makes you want to run one more round without sitting at a desk.
That “just one more run” feeling hits hard
At its core, Castle Away is a roguelite autobattle castle builder, but that description doesn’t really capture the tension.
You start small. Just a 3 by 3 grid. It looks harmless.
Then you begin placing structures. A Monument next to Archery suddenly boosts damage. Walls start stacking defence in ways that feel almost unfair. Banners tweak cool downs across entire rows. Every placement matters. Every mistake sticks.
And the wild part is how quickly things spiral. You think you’ve built something solid, then enemies start scaling, and suddenly your “perfect” setup feels fragile.
Builds that make you feel smart… until they don’t
This is where the game really gets its teeth in you.
You can go full tank. Stack defences, build a Bulwark, become nearly unbreakable. But then you realize you’re not killing fast enough, and enemies start piling up.
Or you flip it. High damage, risky plays. Ballistas, harpoons, flamethrowers everywhere. It looks incredible. It feels powerful. Until something slips through and wrecks your run.
Every choice has weight. And due to that, every run tells a story.

The Castle Away pressure never lets up
Here’s the twist that keeps your heart rate up.
Every fight you pick pushes a demon boss closer. You’re not just building. You’re racing a clock you can’t see. You start planning routes, skipping fights, chasing better loot, trying to out think the system.
Then the boss shows up, and suddenly everything you built gets tested at once.
Win or lose, you know exactly why.
More depth than you expect
The update didn’t just add platform support. There are tons of small fixes and improvements pulled straight from player feedback, and you can feel it. The roguelite autobattle castle builder game is smoother, tighter, more responsive.
And content-wise, there’s a lot to chew on. Around 50 structures with upgrades, 30 banners, 30 boons. Enemies range from standard monsters to five major demon bosses. Then you’ve got different encounters like shops, towns, and weird characters that can completely shift your run.
It’s the kind of system where you keep discovering new interactions hours in.
The playtest window is your shot
The open playtest for Castle Away is live now and runs until May 11th on Steam. That’s your window to jump in, experiment, and break things before full release in 2026. Now coming to Linux PC, Mac, and Windows.
If you’re into systems-driven games, if you like optimizing builds, or if you just want something that respects Linux and open sources setups, this is worth your time.
