Havoc Engine Toolkit
A downloadable toolkit
The Havoc Engine is a set of rules that underpin the phenomenally popular Eat the Reich and the much less popular Goat Crashers and Havoc Brigade roleplaying games.
Havoc is: short-form, over-the-top, and gives players the bulk of narrative authority.
Havoc believes players should do the fun thing immediately and then find another fun thing to do based on the first fun thing. This engine is more candy than you should eat. This engine is a greased pig. This engine is a drum kit for your seventh birthday. This engine is Friday night forever.
The Havoc Engine Toolkit breaks down the core elements of the Havoc Engine and present them to you so that you can understand how these games work and why, and see which bits you want to rearrange, remove, or replace to make the game you want.
It also guides you to design your own original game using the engine with a series of directed questions and exercises. By the time you’ve read the toolkit, which takes maybe an hour, you won’t just be primed and ready to make a game that’s Unleashed by Havoc, you’ll be most of the way there.

I love this but the form on page 3 (Give them each a speciality…) doesn’t seem to be working. In adobe if you type in the form it’s in the middle of the page and the font becomes progressively smaller rather than wrapping on to the next line. In iPad iOS the text is again in the middle of the page but if you type more than one line it disappears off the edge (never to be seen again?) anyway, not sure if there is a fix for this. And BTW, I love that you have shared this!I’m having a great time with it designing what I hope will be my first game.
I was looking through this today and I noticed a two things:
- The link on page 32 of the Toolkit to go to rrdgames.com/havoc-games actually goes to http://%20rrdgames.com/havoc-games
- The link on the last page of the workbook to the Discord is invalid/expired.
I was hoping to take part in the Jam this month, but other things got in the way :( Hopefully I can still put something together outside of the Jam!
Ooh, thank you for letting us know! Something always slips through.
Here's a Discord invite that should work if you'd still like to join the server: https://discord.gg/B7QCYWCVfK Life gets in the way often, but we have a havoc engine design channel year round :]
Yeah, it is always hard to catch everything. Thank you for the link!
