Or was it introduced with the new operation? I just noticed last night after signing in my main and secondary accounts for split-screen Horde that there was a “Player 3 press pause button to sign in” prompt after that, so I dug up another controller, signed that in as a guest, and then I was able to take all three of them into the game!
If this is a new operation feature, then I’d like to say it’s a very welcome one. I’ve been annoyed since Gears 4 at being limited to two characters for split-screen Horde, and this plus the return of duplicate classes makes me one happy lone wolf.(Even if I’m still not gonna last long…)
