Funcom's newest brain-teaser for The Secret World? We haven't, and we'd take kindly to whatever tips you have to offer.
What's that, you say? You didn't know there was a new TSW puzzle? Well, head to the official Funcom website. Once you're there, single-click on something that isn't a link (the red title text that says The Secret World should work), and then type in the number 33.
If you do it correctly, you should eventually see a bunch of glyphs, and we're assuming they're written in some sort of Runic script. That's about where our knowledge stops, though, so check out the forum thread and let us know what you find out!
