Code vein being more floaty and requiring tighter responsiveness to not insta die from the 1-shot kills all over doesn't exactly allow it to be playable in co-op (past a certain ping)
Long story short: don't play action-adventure games via online co-op, got it!...unless it's a game that isn't being made by people who assume everyone lives in Japan and thus, doesn't need good netcode!
I feel like this comment section is about to explode into a debate like it did with r/Kappa when the FG netcode debate started in that community!
