Stars and Stripes on the battlefield! You can buy the United States Civilization key — a unique expansion for Age of Empires III: Definitive Edition. Take command of the young American nation. Instead of standard politicians, you will advance through the ages by adding Federal States (like Pennsylvania, Kentucky, etc.) to the Union, each granting unique bonuses and shipment cards. Command legendary 19th-century units: from Minuteman militia to deadly Gatling Guns. This is a Global key playable worldwide.
⚠️ WARNING: This is Downloadable Content (DLC). The base game Age of Empires III: Definitive Edition is required on Steam to play.
What is included in the United States DLC?
- USA Civilization: A fully playable nation for multiplayer and skirmish modes.
- New Age-Up Mechanic: When advancing ages, you choose a State to join the Union. This adds 2 unique Home City cards specific to that state to your deck.
- Unique Explorer: The General. Instead of a sniper shot, he can plant an "Inspiration Flag" to boost nearby construction and training speeds, and can build Forts.
- New Units:
- Minutemen: Militia that can be summoned instantly for defense but lose health over time.
- Gatling Gun: A rapid-fire weapon devastating against infantry.
- Ironclad: A heavily armored steamship.

FAQ
1. Do I need the original game?
Yes. Without the base version of Age of Empires III: Definitive Edition, this key cannot be redeemed.
2. Can I get this for free?
Previously (in 2021), it was unlockable via a limited-time challenge. That event has ended, and buying this key is now the only way to get the USA civ.
3. Is there a full USA campaign?
No. The DLC adds only one standalone Historical Battle ("The Burning of the USS Philadelphia"). There is no multi-mission story campaign.
4. Is the USA strong in multiplayer?
The USA is considered very flexible due to the Federal State mechanic. You can adapt your card deck mid-match by choosing the right state for the situation.
5. Is it region locked?
No. This is a Global key, it activates without regional restrictions.
6. Can the General fight?
Yes, he is a strong combat unit, but his main utility lies in the Inspiration Flag which speeds up your economy and military production.
