Stronghold: Warlords — Steam key

Stronghold: Warlords — Firefly's castle RTS heads East

For two decades the Stronghold series built European castles and fed garrisons on bread and ale. Stronghold: Warlords (released March 9, 2021, developed and published by Firefly Studios) moves all of that to Asia: feudal Japan, imperial China, the Mongol steppe and the jungles of Vietnam. You still raise walls, place towers, balance the economy and keep your people fed and content — but the scenery, armies and tactics are now Eastern. Buying from us gets you a global Steam key for the full game, activating in any region.

What warlords are and why they matter

The headline addition that gives the game its name is the warlord system. Independent AI commanders sit across the map with their own keeps. You can bring them to heel by force or diplomacy, upgrade them, and issue orders: one sends reinforcements, another bombards the enemy, a third boosts your economy or your troops' morale. They're essentially living nodes of power on the battlefield, and fighting over them often decides a match as much as storming your rival's main castle. It shifts the series' rhythm — you wage war not only with walls and catapults but with a network of allies.

Gunpowder, a series first

Warlords is the first Stronghold with gunpowder. Cannons, multi-barrel rocket launchers inspired by Chinese hwacha, and powder kegs let you blow open gates and shatter packed formations. Sieges are louder and deadlier: the stone walls that held forever in older entries can now genuinely be cracked by artillery. The series' foundation is intact, though — resource gathering, food and weapon production chains, taxes, the fear and joy of your population, and careful fortress layout.

Campaigns and modes

The game has five historical campaigns walking you through key moments of Eastern history: the unification of China under its first emperor, the rise of Genghis Khan and the Mongol horde, the campaigns of Tamerlane, and the conquest of Vietnam. Beyond the story there's a free-build mode with no military threat for players who just want to craft a perfect fortress-city, standalone siege maps, skirmish with free unit placement, and multiplayer for several players. This key covers all of it — it's the full base game, not a cut-down version.

• 🏯 Five historical campaigns (China, Mongols, Tamerlane, Vietnam)
• ⚔️ Warlord system — subjugate and upgrade AI commanders
• 💥 Gunpowder: cannons, rockets, powder kegs
• 🏰 Classic Stronghold economy: food, weapons, taxes, popularity
• 🌐 Free-build, siege maps and multiplayer

Edition and what's included

You get the full Stronghold: Warlords game for Steam. All five campaigns, the modes and the base map set are already inside — no extra purchase is needed to play through. The separate story expansions and soundtrack that Firefly released alongside the game are not part of this key: this is the base game specifically, and it's enough to finish all the core content and play online.

How to activate the key

Activation is the standard Steam flow: open the client, click "Add a Game" bottom-left → "Activate a Product on Steam", enter the code you received, and the game lands in your library. The key is global, so there's no region to match and no VPN required. Once activated the game stays on your account permanently, like anything bought on Steam.

Who it's for

Warlords suits players who enjoy thoughtful RTS sieges and base-building over twitchy micro. If you raised castles in older entries, this shares the same DNA with fresh mechanics and an Eastern setting. If you're new to castle strategy, it's a friendly entry point — the rules are taught through the campaigns. Check our neighbouring strategy titles too, such as Stronghold Definitive Edition and Stronghold Crusader Definitive Edition from the same Firefly studio, or the genre classic Age of Empires II: Definitive Edition.

Quick answers

The key is global and activates everywhere. This is the full game, not a DLC. The game targets Windows; on Steam Deck and Linux it runs through Proton, but that isn't an official developer platform. After payment you get a code, activate it on Steam in a minute — and the fortress is waiting for its commander.
