The castle-building sim is back. At the PC Gaming Show on June 7, Firefly revealed Stronghold 4, a brand-new entry in the long-running medieval strategy series - and this time it is a prequel built from the ground up on Unreal Engine 5. A free demo lands on Steam on June 23, with full Early Access following by the end of 2026.
After a few rocky modern installments, Stronghold 4 is leaning hard into what made the originals click: building a thriving castle economy, juggling your population's needs and defending your walls when the inevitable siege rolls in. The Steam page is already live with first screenshots and details.

A voiced campaign and a shepherd's rise
Stronghold 4 puts you in the boots of Penryn of Wethel, a humble shepherd who climbs the ranks to become a lord and challenge the most powerful rulers in the land. That story runs through a full 22-mission campaign with a voiced cast that includes Ben Starr, Samantha Beart, Walles Hamonde and Harry McEntire - a notable step up in production for the series.
The game adopts an isometric perspective and adds systems like unpredictable weather that can swing the fortunes of a settlement, alongside the resource chains and worker management that define a good Stronghold game.

Multiplayer sieges return
Competitive players are covered as well. Stronghold 4 supports online multiplayer for up to eight players in PvP skirmishes and cooperative battles against AI opponents - the kind of castle-versus-castle warfare that kept the classics alive for years.
Try it on June 23
With a free demo arriving June 23 and Early Access slated for late 2026, Firefly is giving fans an early hands-on before committing. After years of the series searching for its footing, a back-to-basics prequel with modern tech and a proper story campaign is exactly the pitch longtime Stronghold players have been waiting for.
