Alone in the Dark is a set of simple Solo play rules for Blades in the Dark.
They use simple tables to replace the GM with dice rolls and your own improv. skills. What makes these rules unique is that they stay as close as possible to the core Blades mechanics so you don't have to 'stop playing blades' to use the GM Emulator and then have to get back into character.
If you have played Blades in the Dark then you can use these rules. If you are familiar with using Fortune rolls then you will instantly recognise and understand the logic behind this supplement.
