[Update]: Sigil will be coming this May 31st alongside 9 brand new Doom maps.

John Romero recently announced that he will be revealing his latest project on December 10th, the original Doom's 25th anniversary. Given that him and Adrian Carmack have already tried to Kickstart Blackroom, a Doom inspired FPS, I fully assumed that this big reveal would finally give us a taste of what they've been working on these past two years.

As you can probably guess from the title alone, I was quite off the mark. Instead of revealing Blackroom to the world, John Romero has instead announced SIGIL - a lengthy and free campaign mod for the original Doom. While the details are few and far between, I can tell you that SIGIL will contain nine singleplayer levels and nine deathmatch levels, and that the action will be picking off immediately after the fourth episode of Doom.

While the mod itself will be entirely free, there are some pretty nifty physical goodies you can pre-order before December 24th. There will only be a limited amount of these boxes produced, so if you're curious, do make sure to give the official website a peek.

As for SIGIL's release date, you can expect to see it and its boxed sets at some point mid-February, though no exact date has been given just yet. Once more information becomes available I'll make sure to let you know, but until then I would highly recommend you celebrate Doom's anniversary by checking out Doom 2016 - it's pretty damn good!
