So this is a thing that happened.
Usual disclaimers apply to anything coming from 4chan. Up to and including an obscene haiku about Zer0.
I’m toying with a D6-derived version, but the idea has merit in general. Other front-runners for a system to hack include DH D100, 4e, and Shadowrun. Now off to work a character sheet.
Only problem I can think of is dealing with the guns, since d6 is so abstract about weapon damages
Update: up to four pages of stuff not counting the basics of good old D6.
