That is a online multiplayer aspect of the game so I highly doubt it. I know if you disconnect from the Internet you cannot play it. I have also tried messing with different stats using both the CoSMOS editor from here and cheatengine and if you modify something such as money and then try to use it you will get disconnected.
That makes no sense since ive seen no real multiplayer at all
Thank You for testing and checking the trainer.
I don't really understand it either. I think it has some sort of leaderboard ranking system so they (Edios) consider it to be a type of multiplayer. Maybe someone else has had better luck but like I said before I have had no luck getting any of the changes I made in Breach mode to stick, and if you disconnect from the Internet you cannot play it.
