I host all kinds of Warhammer 40,000 Battle Reports on my Youtube Channel. Below you can find links to my different types of reports, as well as rules for the custom scenarios you may have seen in some battles!
Be sure to check out my YouTube channel to see them all!
Playlist Link: Battle Reports
Here you can find rules and outlines for all of the custom gametypes I come up with so you can play them yourself! All of these custom scenarios have at least one corresponding battle report where I try them out with my friends!
If you have any suggestions or ideas for custom scenarios that you want to see us play, email an outline to firstname.lastname@example.org
