Interesting. So clips for the WWE games darken the screen at certain points. ...although, LA Knight was busted open already, but I couldn't tell cause while there was a red flash on the screen, I saw zero blood.
I think the reason it went dark for a moment is cause the game recognized I hadn't pressed a button so it was gonna stop itself. Since it was just me simulating the match and not actually playing.
Kinda surprised you didn't go for one of the CAWs that were modded from the PC version, like the Bray variants from WhatstheStatus. And no, downloading and using them doesn't get you banned.
