The alpha version of the first solo adventure for Heroes Against Darkness, The Sundered Tower, is now up on the rules and downloads page of the website.
The solo adventure has pregen characters, a gamebook section, five combat encounters (each with their own maps) and a bunch of ability tests (plus excitement and adventure). It's still alpha at the moment as it'll go through a bit of playtesting before we call released.
As ever, drop me an email or comment with any feedback.
You can find The Sundered Tower and the full rules over at the downloads page: http://heroesagainstdarkness.blogspot.com/p/game-rules-download.html (http://heroesagainstdarkness.blogspot.com/p/game-rules-download.html)
