If you did not already know, ArcheAge: Unchained is an upcoming version of the fantasy MMORPG which will use the new Buy-to-Play business model, doing away with many pesky Free-to-Play issues. Publisher gamigo today announced that gamers can freely experience the full content of Unchained, the new features and the improved graphics of the upcoming release update Shadows Revealed. To gain access, a registration on Glyph is required. The test server closes on 13 October, before the official launch of Unchained on 15 October.
