Having a hard time getting the head parts for your Zeke?
The easiest way to get the head parts is at the PUPA BATTLE mission.
We also suggest you put on the BATTLE uniform so that you can bring 3 primary weapons.
The 3 missiles: FIM-43, LAW and C.Gustav are enough to put it down. Don't forget to bring supply MK just in case.
During the mission, make sure you hit nothing but the AI pod only. Once the pupa falls, climb up to the pod. Instructions will be given. You also have to make sure you get an S-Rank by completing the mission within 5 minutes.
We completed all 5 head parts within 4 consecutive missions! Good luck!
