Normally when a new trailer arrives for a game, we post it here and you can watch it at your leisure. Or not, we’re not the boss of you. This time however, is a little different.

Frogwares, the team behind new Lovecraftian horror The Sinking City, has indeed released a new trailer for its game, but you’ll have to work for it. Considering the game revolves around mysteries, it’s a neat idea to have players solve a little mystery as part of a clever PR campaign. Want to see the clue? Well, here you go:

It comes with a riddle:

So, Mr. Reed. Sit back and take a deep breath. Tell me – do you really want to know the truth? If so, like Ceaser, look at what you see, move forwards, count to 5, and say what is revealed….But be wary of what might happen next.

If you can work out the answer, head here and enter only the solution in the comments.

If you like what you see, you don’t have long to wait until The Sinking City launches on PlayStation 4, Xbox One and PC on June 27th. Switch fans will have to wait until later this year.
