I have a video and a pic of him admitting to using script mods in halo 5. If u wanna see them tell me how to show you. Something has to be done about this
As far as I’m aware there is no way to mod on the Xbox One, scripts or otherwise. I wouldn’t be too worried.
If you think he is cheating OP, file a report against his gamer tag and the Xbox Live team will look into it
