With some of the rules changes to version 4, I need to add information to the character sheet. I went ahead and played around with the layout and style while I was changing content.
Most notably, Contacts have become a key mechanical feature. They continue to have a bonds/grudges system with bonuses and complications, but they also effectively take the place of expert cohorts from Blades in the Dark.
With the content changes the character sheet will be two pages. While it moves away from the 1-page simplicity of the Blades model, it lets me fit the mechanics into the sheets without overcrowding. Essentially you'll have a main character sheet and a downtime character sheet. That sheet will allow you to track everything downtime related:
Basically the data you don't need during missions (i.e., the bulk of play).
As in all things, the new character sheet format is in the testing phase and still open to future updates.
