Chapter 12: All That Remains
Once you approach the estate after clearing out the rats in the road with two lanterns, you'll see a wounded soldier sitting against the wall with a lantern (he’s hard to see but you'll hear 'we are not alone'. On the other side of the cart you’ll see the other one. The goal is to get through the main gate and past the rats without having them kill both soldiers.
Head towards the first solider and craft two Odoris. Throw the first Odoris at the rats in front of you, and run to the light at the inquisition cart. The second soldier is here. Throw your second Odoris behind the group of rats between your location and the gate in front of you. Run to the gate and hit to go through the gate. If you fail or mess up, just restart the checkpoint. To the left of the second guard is an upgrade station, chest and some materials so I’d suggest heading that way first. It's also a handy checkpoint
