Parts for the infusion pump

After bringing three Empty flasks to Shura the Gynecologist, he tells you that Perfusor will also need two batteries and a control circuit from a Freedom exoskeleton. Vitya the Hologram was able to find a key that removes the teleports at the Fiery Cave; maybe you'll be able to find an exoskeleton or batteries there.
The "key" can be found next to a quarry, in a [ place where a meteorite fell long ago], near a pile of rocks. It looks like a manual teleporter.
You also give him Fang's map to make a fake copy without transition notes, for you to give it to Skygazer later.
== Walkthrough ==
=== Key ===
Travel to the [ radioactive lowland]. The key is located near a pile of three rocks, with some skeletal human remains.
After picking it up, you should get the message that the teleport at the base entrance has been removed.
=== Fiery Cave ===
Head over to the [ highland swamp] and enter the water. The entrance should be under the anomaly in the middle; beware of the frogs living in the swamp, and don't attract the Avengers from their place nearby.
Drop down the hole under the water, and navigate the tunnel, including the fiery section, up to the hole under your feet. Jump over it and in the next chamber with a working generator you'll see Pilgrim. 
Talk to Pilgrim and ask him about the parts for the Freedom exoskeleton, and how to approach Avenger snipers in a stealthy way to get the reagents for the Perfusor. Instead of the control circuit, Pilgrim will offer you a tape recorder for parts.
As for the Avengers, Pilgrim will send a fake message to Chimera, their leader, about a new man looking for mercenary work. This will let you approach them for the Perfusor reagents.
Be sure to search Pilgrim's chamber and break a crate behind the generator, there's a SVD "Long-Range" inside.
Navigate the cave to the next chamber with a bed; there are two circuits on the floor, they are hard to spot.
Be also sure to loot a box nearby, it's full of ammo.
Navigate to the next chamber with a couch and a radio. Pick up two batteries and the teleport deactivator. There's a sniper rifle in a box nearby.
=== Infirmary ===
Report to Shura, and give him the batteries and circuits. Receive back both Fang's map and its fake copy.
You also need to head over the Avengers camp, which is marked on your map.
