One Page 40k
One Page Rules has their one page rules version of 40k and Kill Team up on their website. They’re working on rules versions for Titanfall as well.
From the website:
Right now we have released two projects (One Page 40k and One Page 40k Kill Team), which are great rulesets to create exciting battles. Kill Team in particular has been a blast, which has features such as a “push” mechanic that let’s you kick your enemies off of buildings or into deadly machinery, and we have been getting a lot of positive feedback.
