King under the Mountain is a simulation-based strategy/management game where you design, build and run a settlement in a fantasy world. Then, once you're up and running, you can send out groups of adventurers to explore and loot other players' creations, playing out through turn-based tactical combat. You start a game on a randomly-generated area map with a few settlers, tools and other provisions, and slowly grow into a self-sustaining village, town, or eventually, a city. You play as one of several fantasy races each with their own unique gameplay mechanics.

I'm a solo developer who's been working on King under the Mountain for 5 or so years now, most of it documented right here on IndieDB! I describe it as a simulation-based settlement-building strategy game set in a fantasy world. The gameplay is inspired by Dwarf Fortress, The Settlers and Dungeon Keeper, and it uses the visual style of Prison Architect and Rimworld.

After a long journey (and perhaps just as far still to go to 1.0 release), today the game has launched on Steam in Early Access. Here's the most recent trailer:


And the store page is at Store.steampowered.com

Can't download demo to pay yet, but it has several levels like DF or just one like the old DF?

Ah but the beer is coming, with a very detailed production chain and a major part of the economy! :) Just not in this version sadly, but the next major one I'm sure it will be.

Hi, I was really enjoying playing your game. Even so early in development the mechanics are tight and fun. However, the demo crashed shortly after I started using it and I noticed that I was up to 3GB of memory usage from the game. I think you might have a memory leak :(

Here's a quick look at memory management under the hood - it's very spikey due to the Java garbage collector but over time seems to use the same amount of memory for the duration, dropping down to about 250MB on average. How much memory do you have on your machine? Any info helps!

Thanks a lot for bringing that to our attention! Looking into it now! The game does seem to hover around 2.8GB of memory usage normally (not been at all conservative with memory usage at this stage) which is a lot but shouldn't be a problem for modern desktops/laptops. Will do some debugging now to see if I can find a memory leak.

Hi, I have 32GB of memory so it shouldn't be a problem at all (and I'm not even entirely sure it was the cause of the crash - I looked for a log file just now but couldn't find anything). My suspicion is that not enough memory is being assigned to the JVM which could cause it to crash if memory usage spiked. I'm really keen to make a video on this game so I'll try again this evening (GMT+13) and get back to you with an update.

The windows demo is using 32bit java. It doesn't matter how much ram your computer has 32bit java will not be able to address more than 4GB, but in most OS it is closer to 3GB.

Actually every platform only comes with a 64-bit launcher, mostly due to this memory constraint.
