Dr. Spara has an idea for a rocket navigation system and needs your help. The first item she needs are Tork brains, so head to the waypoint and keep killing the Torks within the area until you manage to procure three brains. The next item she needs are some stalker wings. Note that you’ll fight Stalkers along the way to the waypoint, but only those within the highlighted area on your map drop them.

After acquiring the wings, Spara mentions that she needs some stalker blood, which you can get from the exam tables in the area. You need to just turn the wheel at each spot, wait for the blood to fill up, then grab the container. The first one is north of where you got the wings, while the second is just south from the same position. The last one is located just before you get to the outside area with the stalkers.

Just interact with the container, wait for the blood to fill it, then you can grab the stalker blood.

Return to Spara and she’ll ask you to apply the wings to the three rockets, then you’ll need to put the canisters of stalker blood on each one. Place the Tork brain in the southern rocket, then go to the control panel and fire it. Once that’s done, Spara says to go get some human brains for her experiment.

Two waypoints will now appear on your map, but you only really need one unless you mess up. In order to get the brains, you’ll need to get a headshot kill on the Dahl soldiers. The only problem that might happen is that any elemental damage might negate the brain from dropping. Return to Spara when you get both and place the human brain into the rocket.

Go to test fire the rocket and there will be one more task for you to do, which is to combine the Tork brain and human one. Go to the blender and place both brains in, then she’ll ask you to freeze it. If you don’t have a cryo gun, there will be one in the chest to the left of the blender. Grab the frozen brain and place it in the rocket, firing it afterwards. Talk to Spara to finish the mission.
