Thank you! Overdrive is an idea I lifted from the Household /Outgunned systems by Two Little Mice (I was heavily influenced by their use of Conditions as well).
Mutations I still need to figure out. I know I want them affect the Agent in both negative and positive ways but I'm torn on how often you should get them. If you are getting a Mutation every time you hit your 5th T.R.E.A.T. box, then you will have your max Conditions in no time and that kind of defeats the purpose. So I think it needs to be more of a roll to see IF you get a Mutation. We'll see.
Anyway, thanks for the feedback!
