The Order: 1886 - fight skip in Chapter 1-3
Whoa, an actual sequence break in The Order: 1886! ...No, this still doesn't make it an interesting speedgame.
After the tutorial during Chapter 1-3, the level opens up to a wide battle area. You'd normally have to fight the fight, witness a hostage situation take place and then watch 25 seconds of cutscenes as you and Igraine defuse the hostage situation.
The sequence break is basically running past the fight and getting to the hostage situation early. The hostage taker is surrounded by a pointlessly wide invisible collision to prevent you from running past him before he closes the door. And normally you can't. Trying to get close to him from the right or front results in just getting blocked by the invisible wall. However, you can squeeze past him from the left side, where there's seemingly less invisible wall.
Once in the doorway, you should get through fairly reliably if you just keep running / sprinting straight forward.
Chapter 1-4 begins like normal when you walk past the next corner. I played up until Chapter 1-7 and things still worked normally, so I'm fairly confident in saying that the game works normally after having done this skip.
It's hard to say how much this skip really saves time, but it might be around 2 minutes, I guess. After all, the fight is relatively long and there are some cutscenes to watch afterwards too.
