Funcom's flagship MMO, Age of Conan has become free-to-play, thus the Unchained moniker.

Unlike the previous extended trial, which allowed players to play until level 20, Unchained will allow all players to reach the level cap. Of course, there will be other limitations. Free players will only get four classes, no sieges, no alternative Advancement, or offline levels. Players can also subscribe for $15/month as usual for full access to all content.

You can find more information and start playing at the Age of Conan: Unchained website.
