So uh I was looking though the files for the game and found "payload.exe" payload is used my viruses alot so play at your own risk
It is included by default with NW.js files used by the RpgmakerMV engine.
I think you're mixing stuff up. Payload refers to the actual malicious parts of a cyberattack, be it a virus, worm or ransomware. Pretty sure "payload.exe" is harmless.
Hmm.. maybe your right.
