Bioware has revealed the PC centric RPG "Shadow Realms" 

After weeks of mysterious, creepy teaser trailers like this and this, Bioware has announced something concrete at EA's Gamescom press conference Wednesday.

The new  role-playing game is influenced by old-school pen-and-paper games, Hickman explained. Shadow Realms will feature online and dynamic four-player co-op against a single playable enemy who controls "every aspect of the game."

"Shadow Realms has its genesis in old school Dungeons & Dragons. When I first started designing BioWare RPGs back in the 90s, what drove me creatively was the desire to give players the experience I had while playing pen and paper games as a youth," writes James Ohlen on the Shadow Realms website. "The great storytelling, the feeling that anything could happen-these were experiences that you couldn't find in any other game. And the great thing was that these adventures never had an end. A good Dungeon Master could keep a story going for months or even years."

"Shadow Realms" will release sections of the story over time, episodically. "It is a game that finally fulfills that fantasy of a never-ending RPG where the players meet up regularly to keep their epic adventures going for as long as they want. All the enemies, traps and challenges are squarely in the hands of another player, who controls them just like a Dungeon Master," Ohlen continues.

"This game brings us back to our roots in the realm of classic Pen and Paper RPG, but also delivers something that's completely new and innovative for our fans," said Hickman. "Shadow Realms is a new BioWare RPG that has the hallmarks of all BioWare games with a rich story, a unique world setting and deep combat progression, but built as an interactive experience that evolves the genre and broadens the appeal to online gamers all over the world."

According to the press release,  "Modern Heroes on Earth are being awakened and recruited, because of magical powers they never knew they had, to fight in a new and dangerous war against the Shadow Legions of Embra. The Shadow Legions, who have been battling on Embra for years against the members of the Radiant Empires, have gained new strength with the coming of a powerful, unknown force that we call the Shadowlords. And, they have just figured out how to leave Embra and invade Earth."

BioWare's horror action title Shadow Realms is in online action RPG due to hit PC "late next year," in 2015.
