MercurySteam made the respected Castlevania: Lords of Shadow, and also its...less respected sequel. Still, it's a developer worth keeping an eye on: there was a lot of technical and artistic wizardry in that first game in particular. A few months after posting a mysterious teaser image on its website, the dev has replaced its entire site with a teaser for its mysterious new sci-fi game.
