Zeboyd Games announced that a free DLC expansion for Penny Arcade's On the Rain-Slick Precipice of Darkness 3 will be released on Thursday, October 25th, accompanying the launch of new ports for Mac, iOS, and Android devices.

"The Lair Of The Seamstress" DLC for Windows and XBLIG adds a new post-game bonus dungeon designed to challenge players who have leveled their classes above level 40. The update also includes a new costume pack that turns the playable cast into zombies.

Those who purchased the Windows version of Rain-Slick 3 via Steam will receive free access to the Mac version when it launches on Thursday. Zeboyd also notes that the mobile ports of Rain-Slick 3 will feature "much better touch controls this time around than they were with the Cthulhu Saves the World port."

The final free DLC release for On the Rain-Slick Precipice of Darkness 3 is scheduled for release in December. The next entry in the series will launch early next year.
