Chapter 1 starts off with a conversational choice and a quick QTE
and then some more conversational choices after which you'll have to press
to jump on a horse.
Once on the horse you choose to help Petra or Gabriel and a new scene will load.
Now whilst riding on the horse you'll be running away, use
to move left and right to avoid the monsters and
to attack when behind a monster. After jumping the gap you will need to avoid the purple rays from the monster. I stayed left then moved right and used
to jump two gaps when prompted. After some talking theres a bunch of movement QTEs to press.
After the bridge is destroyed and the Endermen start to help you'll need to mash
to build a new bridge, once you're across the chapter is over.
