OK. I just uploaded my Gamma World 2e sheet. The PC sheet is working, and the NPC and robot sheets are still in progress. Pull request is here: <a href="https://github.com/Roll20/roll20-character-sheets/" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/</a>... It does attack rolls, skill checks, has a place to add mutations notes, level advancement and status advancement. I have started to track stat modifiers separately, so that these will calculate automatically when you add the appropriate mutation, item, or plot line info.
