In online competitive games, players not only have to worry about cheaters using third-party programs, but also the rampant issue of players rage-quitting the match when their team falls behind. Although game officials usually impose penalties for such behavior, Marvel Rivals players recently discovered an unexpected loophole.
According to streamer LytePk, some players have recently begun exploiting Marvel Rivals’ anti-cheat system by quitting the game directly when they’re about to lose, without facing any penalties. He also urges NetEase Games to resolve this issue as soon as possible.

The trigger method for this exploit is also very simple. Players just need to temporarily exit the match, return to the game lobby, and then, while the match is still ongoing, place the modified config file into the game files and reload the game. This action will cause the entire match to be cancelled directly. However, the root cause of all this is actually NetEase’s official anti-cheat measures.
Before this vulnerability was discovered, many players would resolve the game’s optimization issues by “modifying backend configuration files,” such as increasing frame rates to make the game run more smoothly on their own computers. Although this behavior was not malicious and did not cause serious fairness problems, the situation gradually began to take a turn for the worse.
Soon after, players also began discovering that these configuration files could disable all the complex visual effects in Marvel Rivals maps, making enemy hero positions much more visible and thus giving them an advantage in competitive play. This chaos ultimately forced the development team at NetEase to issue a formal warning, officially announcing that they would penalize such behavior, while also adding a detection mechanism that would cancel the entire match whenever the system determined a player had modified their configuration files.
But as the saying goes, “The more cunning the defense, the more devious the exploit.” This so-called “anti-cheat mechanism” ultimately ended up being abused by some players, allowing them to directly modify backend configuration files on the spot when at a disadvantage, forcibly interrupting the entire match—without having to suffer any penalty for leaving early. It’s essentially an attitude of “If I can’t win, nobody gets to play.”
This is real here’s proof. You can see we are spawn camping and then the player Murder Rate leaves the game. In the chat his teammates say “gg game cancelled” and he comes back to the game and it cancels because of “cheats”. What he did is enable a config… FIX @MarvelRivals https://t.co/OilOIGvhno pic.twitter.com/8DVTqZICpw

Although NetEase has not yet responded to this, many players believe that they will next impose harsher penalties on those who modify configuration files. However, this also directly impacts players who only modified the game to make Marvel Rivals run more smoothly—after all, this exploit for avoiding losses is far too easily abused, and it’s hard to determine the intent behind the modification.
