When I read the synopsis I thought this would be a near 1:1 overlap with my CRAT about alt-reality FIST operatives. It's a good thing for me it isn't, because Red Mirror is better than my pamphlet, and since it's part of a numbered series I appreciate not having to pull it down.
Fun insertable mini-bosses (bosses?) that the players are going to have immediate buy-in on the fight with, and where the players have done most of the work for the Ref already? Beautiful.
Well laid out, fun "Kill Your Shadow Self / Inner Demons for a custom Level!" mechanics, good use of FIST-appropriate art that doesn't overshadow the text.
