Publisher Deep Silver is teasing a game in the Sacred RPG series. A new tweet from the company reads, "Blessed are the devout. Hallowed are the pious. The dawn of a new Holy era approaches. sacred-world.com" Use that link and you'll find the image above and nothing else.
My guess: Tuesday you'll see news on a Sacred MMO, though there's the offchance it's a regular Sacred game as well.
The Sacred games, if you're not familiar, are excellent traditional hack and slash RPGs but with several unique gameplay twists like combos. Longtime franchise developer Ascaron kicked the bucket a few years ago, so it'll be interesting to see who's stepped up the plate, or if by some miracle the team has reformed, if only in part.
