The Lost Hall of Tyr: A 5e Adventure (Dungeon Grappling support) is Gaming Ballistic / +Douglas Cole 's 2nd Kickstarter, the first being Dungeon Grappling.
Now, if you don't know what Dungeon Grappling did is it brought usable grappling rules to the various D20 systems - everything from Swords & Wizardry / OSR through 5e.
So, what is the Lost Hall of Tyr?
Lost Hall of Tyr is an adventure scenario for Fifth Edition, targeted at four to six characters of level 3-6. It offers support for the alternate grappling rules from Dungeon Grappling, including an introductory two-page quick start.And at $8k raised? It gets converted to Swords & Wizardry ;)
I'm looking forwarded to the S&W conversion...
