Solo developer Klenisho Games has announced The Citadel Must Hold, a fantasy base-building RTS coming to PC via Steam in 2027. The game combines classic RTS hero and army management with wave-survival mechanics, where players defend a citadel against monster attacks while exploring the surrounding wilderness.
Between waves, you venture into various biomes to fight enemy encampments called Places of Power. Defeating these grants rewards that can strengthen your hero and army, unlock new unit types, or reshape the map. Ignoring them comes at a cost—the enemy camps will raid your citadel if left unchecked.
The game features classic RTS-style combat with powerful heroes and multiple unit types, dozens of enemy varieties that attack in tides with thousands of monsters, and exploration across multiple biomes for loot and upgrades. An alpha playtest is available to request via the Steam page.
