Rules for Chaos/Cthulhu Type Horror?

[simrion]

I tried searching the site but my "search-fu" is weak and I'm not even sure what to search for. I know there were some rules supps published during the "OSR" excitement years back that covered chaos and horror rules/resources for OD&D. Off the tops of your brilliant minds here might you suggest one or more resources I can pursue? Many thanks in advance!

I think you might be looking for Labyrinth Lord's Realms of Crawling Chaos.

Recheck your spelling of Cthulhu. Thread title typo (now fixed) is "Cthulu" so that might be why you can't find it?

There is a thread here with similar content:
odd74.proboards.com/thread/11097/why-od-cthulhu

ODD74 has a sub-board under Fiction called "Lovecraft and the Mythos" with a couple dozen threads:
odd74.proboards.com/board/142/lovecraft-mythos

If you like my S&W White Box rules, there is something called "Eldritch Tales" which is advertised as Lovecraftian White Box:

Also, a couple good blog articles:
oldschoolroleplaying.com/cthulhu-in-dungeons-and-dragons/
zenopusarchives.blogspot.com/2013/01/the-cthulhu-mythos-in-d-in-1970s.html

As to already-published works, look into the "Call of Cthulhu" RPG. It's a d100 based RPG instead of d20, but that's an easy fix. Monte Cook wrote d20 Cthulhu, obviously based on 3E so you would have to convert some. "Silent Legions" by Kevin Crawford is OSR Cthulhu. "Cthulhu Hack" is based on "The Black Hack" RPG and I haven't seen it but hear good things.

Also, "Mythos and Mayhem" advertises itself as OSR Cthulhu:

Hope that helps a little.

The old Ravenloft books included rules for fear/terror/horror checks.

Just as an aside, I LOL'd reading your comment and then looking at your profile picture, which clearly is a visage of fear and terror!

For already-published works, don't forget Night Shift: Veterans of the Supernatural Wars!

The core book covers all kinds of horror and has rules for corruption, madness, and the like.

The Night Companion Sourcebook offers a bunch of Lovecraftian creatures and expands on Cosmic horror elements.

The Realms of Crawling Chaos book is great. Nothing groundbreaking or must-have, but it's solid meat & potatoes with a super convenient presentation. It's probably the OSR supplement/sourcebook I've used the most over the years regardless of which system I'm running.

The Realms of the Crawling Chaos was just what I needed. I picked up a copy!
