This chapter is a complete guide for To Old Acquaintance errand. Here you can find tips that will help you to finish this quest in the most beneficial way.
Activating the errand
The errand appears in your journal after the conversation with the woman called Gera, she can be found in Hunter's Gathering. Gera asks you to find her husband who was supposed to get back to the camp but he hasn't contact them for some time. You must go to the place where he was seen for the last time and search information about him.
In the place pointed by the marker you won't find anyone. Use Focus to find the path that the man might have use. Follow the tracks that lead to Hunter's Gathering (the southern part). The wagon went right from the path, behind the campfire.
Use Focus to detect the items that can help you in tracking. You can find the basket that could belong to the missing man. Scattered bottles are also part of the tracks. When you get to the chest examine it and then continue to go along the rocks. You can spot a small herd of Tramplers and a campfire which is near them. Save the game and go back to the quest's route. The last hint is the barrel presented on the picture.
After examining the barrel Aloy discovers that Kendert hides in the mountains. Speak with him.
Recover the bottles
The next stage is to recover five bottles of beverage for Kendert. On the picture above I've marked the region where you can search them. When you get to the right spot you can quickly notice the green tag indicating an interaction with an object.
The region, as presented on the picture, is overrun by machines but this shouldn't make the task more difficult. You can use shock/freeze bombs to neutralize them but the machines are very durable so the best idea is to run into them. Tramplers are very flightily and the way they fight is very chaotic. Sometimes they run away, sometimes they charge at you and sometimes they try to use range attacks by digging earth. You just have to use regular dodges when you see a blinking exclamation mark in the corner of the screen and everything should be fine.
If you feel that you are in danger then go on the hill and the machines will almost instantaneously forget about you. What is more, sneaking may be very ineffective because there aren't many bushes here so you will be quickly discovered.
Finishing the quest
When you get five bottles, return to Kendert. A short conversation ends this stage. Then, you must speak with Gera to complete this errand. The woman is now in Daytower so pay attention to quest marker before using the fast travel option.
