An announcement is looming about a new game from Baroque/Ygddra Union developer, Sting. The splash page says "Dept.Heaven Episode IV" with sixteen days left on the counter. The other clue is the URL. Notice how it is placed in the "knights" folder. Sting usually puts each series in its own folder, which suggests this isn't another Riviera remake.
Siliconera wonders if anyone has a guess on what it might be.
