The Celts are coming to Age of Empires Online, and they're bringing some mean weather with them. Snowy tundra that slowly saps your units strength will be a key part of the new missions that the pack will add, and there will be a wealth of new units, of course. Celtic priests will be able to sacrifice deer to help out your forces, and their new hero is capable of infiltrating enemy villages.
The Celts will be available as an army pack that can be bought separately as an add on for the core game, which is free to play. You can sign up for an account and download the client from the Age of Empires Online site if you fancy checking it out. You can read our verdict on launch in our Age of Empires Online review .
