'Aion' and 'RaiderZ' playable at Gamescom

Aion and RaiderZ made playable at this year's Gamescom.

Gameforge is presenting massively multiplayer titles Aion and RaiderZ at this year's Gamescom, the publisher announced today.

This will be the first time RaiderZ is demonstrated to a large audience and made publicly playable. The online role-playing game features action-oriented combat, and a "hunt" for bosses. Gameforge plans to offer this as a free title during the second half of 2012.

Those visiting the Gameforge booth will also get the chance to test out Aion 3.0, the latest major update for the Korean-developed massively multiplayer online game. This will bring a new housing area and mounts to the title.

Gamescom takes place from August 15th to August 19th in Cologne, Germany. Polygon will be on hand to cover the show, its press conferences and GDC Europe.
