It is natural that each project has its own share of hackers and fans to play not according to the rules. And now, it seems, the same fate befell the MMO version of the Action Red Dead Redemption 2 (Red Dead Online). It seems that the time of Halloween has already passed, and skeletons with two heads that beat the players began to appear in a cowboy game, causing decent damage using a combo series. Moreover, according to the players, even after they tried to kill these monsters from weapons, they hid without damage with impunity.
