I'm looking forward to "SIGMATA: Repeat the Signal", the next role-play game released by Chad Walker. It's about fighting back against fascists in a super cool cyberpunk world, and apparently it improves on the previous edition "This Signal Kills Fascists".
Gonna see if I can get a physical copy once it comes out.
