About This Demo

About this demo

This free demo contains the first three chapters of Castellan: The First Night, The Drowned Village and The Burning Keep. Each one has its own enemy faction, elites and boss. The full game will have more chapters. Progress from the demo does not carry over to the full game.

I am a solo developer. If you enjoy the demo, adding the full game to your wishlist helps far more than you might think. Every idea and every criticism is welcome.

The old races have made a deal in the dark: the age of man ends here. Every castle along the border has fallen. Yours is the last one standing.

Fight in real time

You are the castle. Hold the left mouse button to rain arrows on the horde, aim your shots where the fighting is thickest, and release your Ward Pulse when enemies press against the walls. Every kill feeds your war effort.

Play your cards

Your soldiers are cards. Drag them out of your hand and drop them anywhere on the field: footmen to hold a flank, archers behind them, clerics to keep everyone standing. During battle, supply crates fall from the sky. Shoot them open and fresh cards fly straight into your hand.

Cast spells

Four spell slots sit on keys 1 to 4. Snare a wave with entangling roots, slow it with a frost field, melt it with a fireball, or patch your walls with a repair ritual. Charges are limited, so every cast is a decision.

Grow between runs

Losing is part of the plan. Every attempt earns mastery, and mastery unlocks nodes on a sprawling upgrade tree: tougher walls, faster arrows, deadlier soldiers, better supply drops. Open barracks, archery and chapel chests to recruit new units, and complete quests to push your gold economy higher. Then go back in stronger.

March through the chapters

Each chapter is a different enemy nation with its own elites and boss. Walking dead and forest trolls in the first night. Naga, dark elves and harpies rising from the drowned village. Forge dwarves who did not bring torches, they brought furnaces. And worse is on the way.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI tools were used during development to assist in the creation of some pre-generated content included in the game. All such content was reviewed, curated, and edited by the developer before inclusion. Some 2D sprites, icons, and key art were created with the assistance of generative AI tools. Music and sound effects were also created with the assistance of AI audio tools. Localization for languages other than English was produced with AI assistance and reviewed by the developer. The game does not use generative AI at runtime and does not generate any live AI content during gameplay.
