Age of Empires II DE — Steam key

Age of Empires II: Definitive Edition — a Steam key to the legendary RTS

Age of Empires II first launched in 1999 and spent two decades becoming the benchmark for real-time strategy. Definitive Edition is that same classic, rebuilt from the ground up: 4K visuals, re-recorded audio, rebalanced gameplay and a steady stream of new expansions. You raise a town, grow your economy from the Dark Age to the Imperial Age, train an army and clash with an opponent — whether that's the AI, a friend over the network, or a rival on the ranked ladder. Buy a global Steam key from us, redeem it in your own library, and the game is yours to keep for good.

How Definitive Edition differs from the original

This is no token remaster. Forgotten Empires and World's Edge pushed the visuals up to 4K, redrew the units and buildings, re-recorded the soundtrack and voice-overs, added a modern interface and enabled cross-play between Steam and the Microsoft Store. The base version already includes every civilisation and campaign from the classic game and its older add-ons (The Conquerors, The Forgotten, African Kingdoms, Rise of the Rajas), plus the DE-exclusive campaign The Last Khans with extra civilisations. In short, you're getting the most complete version of AoE II ever released.

What you're buying: base game and expansions

This page lists both the game itself (the base key) and the major expansions that arrived after launch. The base key is the full game — you don't need anything else to start playing. Every expansion (DLC), however, installs on top of the base game: first Age of Empires II: Definitive Edition, then the add-on. If the base game isn't on the account, the expansion simply won't run. Here's what each one adds:

• Return of Rome (16 May 2023) — brings the legacy of the very first Age of Empires into the AoE II engine: a separate mode with ancient civilisations and campaigns for Rome, Egypt and Greece.
• The Mountain Royals (31 October 2023) — two new Caucasian civilisations, the Armenians and Georgians, plus fresh campaigns and mountain-region maps.
• Victors and Vanquished (14 March 2024) — a pack of new scenario campaigns (single-player and co-op), built partly from community ideas; it adds no new civilisations, it's a battle-focused content pack.
• Chronicles: Battle for Greece (14 November 2024) — the first entry in the Chronicles line: a self-contained mode about the Greco-Persian Wars with its own units and factions (Athenians, Spartans, Achaemenids).
• The Three Kingdoms (6 May 2025) — five new civilisations (Shu, Wei, Wu, Jurchens and Khitans) playable in every mode including ranked, plus three campaigns set in China's Three Kingdoms era.
• Chronicles: Alexander the Great (14 October 2025) — the second Chronicles release: three non-ranked civilisations and a campaign following Alexander the Great's conquests.

Chronicles (Battle for Greece and Alexander the Great) and Return of Rome are largely standalone modes with their own rules; The Three Kingdoms and The Mountain Royals expand the classic match with new nations; Victors and Vanquished is all about new story scenarios. All of them require the base game installed.

Global key: activating on Steam

The key is global (GLOBAL) — it activates on Steam in any country, with no region lock and no VPN needed. After payment you receive a code. The rest is easy: open Steam, click "Games" → "Activate a Product on Steam", enter the key, and the game (or expansion) lands in your library. For expansions, make sure the base Age of Empires II: Definitive Edition is already on the same account.

Where to play: PC, Steam Deck, cross-play

The game targets Windows, runs great on laptops and is comfortable on the Steam Deck — the controls are adapted for gamepad and touchpad. Cross-play works between Steam and Microsoft Store players, so you can invite friends from either platform into a network match. It supports single-player campaigns, skirmishes against the AI, local and online multiplayer for up to 8 players, and seasonal ranked matches.

Who it's for

If you enjoy thoughtful strategy where economy, battlefield micro and picking a civilisation that fits your style all matter, this is one of the best ways into the genre. Newcomers get tutorial campaigns and helpful tips, while veterans find a deep ranked multiplayer scene and dozens of nations with their own bonuses and unique units.
