About this game
The realm’s surface is cursed by demons. While you are exploring, you discover some sort of crown. As you pick it up, the ground begins to tremble and the surface starts to rise. You find yourself on a massive, floating keep...
Castle Away is a quick-to-pick-up, run-based strategy game focused on crafting combat synergies on your little castle grid. You slay monsters, scavenge for materials, craft structures, and upgrade your keep to ultimately defeat the Archdemon, and purge the realm.
Build your castle
When starting out, your castle base has a 3-by-3 grid to place structures on, which will expand the further you progress. Structures give adjacency bonuses, so where you place is just as important as what you place.
Create synergies
There are plenty of synergies to exploit. For instance, a Cannon Tower receives +1 attack for every unit of defence (we call it Bulwark) that is created by your walls, but it takes some time to charge up. How much attack is your Cannon Tower able to gather before it strikes?
Battle away
Send your castle into battle and watch your strategy play out as combat resolves automatically. Loot monsters and encounters to strengthen your build. Every encounter you choose draws a demon boss closer, until it surfaces to challenge your keep. Plan your route, claim the best loot, and survive every boss to reach the Archdemon.
Craft structures
You'll find materials along your journey that will let you craft and customise your structures. Demolish buildings you no longer want, to create new ones to take their place.
Retry, ascend, and collect
As in any typical run-based game, you will to try and find the best combinations for your run, in order to beat the game. But that's not the end. You will unlock new castle types with unique structures, banners, and materials to arm yourself against higher difficulty (ascension) runs, which will unlock the most obscure items.
Features
Deep customisation: Find over 50 different structures with 3 upgrade tiers, 20 Banner types and many other unique boons to build killer synergies.
Challenging enemies: Face off against 10 different monsters and 5 demon bosses.
Varied world encounters: Discover towns, shops, towers, shamans, lifesprings, plague doctors, and more.
3 distinct regions: Explore the 3 regions of the realm to find all ancient beacons.
Roguelite replayability: Random encounters, a semi-procedural world, and unlockable loot ensure fresh runs.
Team
Castle Away is made by three independent creators: René Slump (Gladiator Manager) designs the deep mechanisms and programs the game. Sim Kaart (Rift Riff, Gladiator Manager) creates art and designs a coherent experience. Matthijs Koster (Rift Riff) crafts sounds and creates music. Tom Schoen leads the game's marketing efforts and sets up vital partnerships.

Demo out now!
Hey all! You can play the Castle Away Demo RIGHT NOW! Thank you to everyone who has wishlisted, playtested, streamed, and followed along. We have spent the last three months iterating on the game's design, and balancing the content to hopefully create a tight demo experience, in which you can craft multiple builds on two unique castle grids. In the demo:2 Regions – explore the Cradle and the Steppes. 2 Factions – experiment with the Stone and Dirt castle grids. 2 Difficulties – were you able to beat the Archdemon on Survivor? Try to beat Explorer. Currently in the main game:3 Regions – the Cradle, the Steppes, and the brand-new Frozen Peaks. 3 Factions – the Stone Keep, the Dirt Keep and the new Obsidian Keep. 3 Difficulties – Survivor, Explorer and the new Crusader difficulty. What we're working on right now:- a new 'boons' mechanic that gives general bonuses - a new 'gargoyles' mechanic that adds a new building dimension just like 'banners' - more encounters on the world map - more monsters and demons - more obsidian structures Have fun with the demo! Wishlist the game on Steam, if you haven't already. And join our discord or jump on the Steam forums to discuss the game, share feedback, bugs, etc.See you in the next update!!René, Sim, Matthijs & TomRead full article on Community Announcements (Sim Kaart)AnnouncementsOfficial
