Castellan is an action strategy indie game for PC that puts players in command of the final human stronghold against overwhelming enemy forces. The core experience combines real-time defensive combat with card-driven unit deployment and roguelite progression across multiple runs. Players defend their castle by directly controlling arrow fire, deploying soldiers from a hand of cards, and casting limited spells while enemies advance in waves.
Gameplay
The central loop requires constant attention to the battlefield. Holding the left mouse button unleashes arrows that players aim toward the densest clusters of attackers. When foes reach the walls, a Ward Pulse can be released to push them back. Supply crates drop during fights, and shooting them open adds new cards directly to the hand for immediate use.
Soldier deployment happens through a card system. Footmen hold lines at the front, archers provide ranged support from safer positions, and clerics restore health to keep units fighting longer. Placement is flexible, allowing quick responses to threats on either flank or at the gates.
Four spell slots mapped to keys 1 through 4 offer tactical options. Entangling roots can snare advancing groups, frost fields slow their movement, fireballs deal area damage, and repair rituals restore wall integrity. Each spell has limited charges, forcing careful timing and prioritization during intense waves.
Game Modes
Castellan centers on a single-player experience built around repeated runs through a series of chapters. Each chapter features a distinct enemy nation with unique units and a final boss encounter. Progress comes from surviving as long as possible in a given attempt, after which mastery points unlock permanent upgrades.
Runs emphasize adaptation rather than fixed levels. Supply drops and card draws introduce variability, while the upgrade tree grows more powerful with each failure. The structure encourages multiple attempts to reach farther into the chapter sequence and face tougher opponents.
Progression and Upgrades
Mastery earned from every run feeds a large upgrade tree. Nodes improve wall durability, arrow speed and damage, soldier effectiveness, and the frequency or quality of supply drops. Separate chests for barracks, archery, and chapel units expand the available card pool over time.
Quests completed between runs boost the gold economy, allowing more consistent recruitment of stronger soldiers. The tree reveals additional nodes as mastery accumulates, creating a sense of steady growth without requiring perfect runs.
Enemy Factions and Chapters
Chapters introduce varied threats that demand different defensive approaches. The first features walking dead and forest trolls. Later sections bring naga, dark elves, and harpies from a drowned village setting. Forge dwarves arrive with furnace-based attacks that test wall repair timing.
Each faction includes elite units and a chapter-ending boss. These encounters reward precise spell use and smart card placement rather than simple overwhelming force.
Is It Worth Playing?
Castellan suits players who enjoy real-time strategy mixed with roguelite elements and direct control over defensive actions. The combination of aiming arrows, managing a card hand, and selecting from limited spells creates a hands-on loop that differs from traditional tower defense titles.
Those who appreciate incremental progression through repeated attempts will find the mastery tree and expanding card collection rewarding. The chapter structure with distinct enemy types adds variety across runs without introducing separate modes.
The game is best for solo players comfortable with learning through failure and refining tactics over multiple sessions. Its focused design on castle defense and card deployment makes it a niche but coherent experience within the action strategy genre.
