I like this a lot. I like the game's premise and the execution of the Havoc Engine integration. The art is so good, it absolutely sells the character concepts.
The stat spread suits the tone really well. The skills and abilities are also very well written for each character. I love the decision to have two separate condition types, physical and social.
I LOVE the heat track. I love it so much that I almost wish that rolled 1's advance the heat track to make sure more heat events happen throughout a session.
The ability to buy skills and guns using Cash was a great decision. I see the other comment about the interaction between heat and cash. I think you could definitely limit the ability to spend cash at a certain heat threshold, but that relationship could also very easily go the other way. Being seen spending a bunch of cash on guns and bulletproof vests is probably a good way to get heat.
The player secrets are a super interesting design choice. Giving an unused secret to Autumn is such a phenomenal way to increase the drama in the story.
I really enjoyed the read. Great work!
