Polarity Switch Day 4 - requirements for eliminate 5 +ve followed by 5-ve hostiles?
Does anyone know if there are any other requirements to complete this challenge beyond what's in the text? I counted five positive enemy kills, followed by 5 negative enemies and the challenge doesn't complete. I bashed enemies with the shield to ensure they switched to the correct polarity before shooting them.
Do you need to avoid hitting any opposite polarity enemies? Or get all ten kills within a certain time or area?
[edit] nvm, just did it on American History. Not sure why it worked in mission but not in open world when spread across different activities.
