Hyrule Warriors/Hyrule Field (Cia)

Since Wizzrobe and Volga in under Cia's control, Cia can start the invasion. With Poes and Lizalfos involved, Hyrule Field is going to go to pieces. Cia won't be involved though so you can only control Wizzrobe and Volga at this level.

Playing in the fields
Start by conquering the middle base as one of your allies, depending on who you choose will start attacking the north west base. Goron officers will show so try to attack them before they reach the enemies base on the south west corner.

Lana and Impa's desperation
Lana is trying to get stop your army from attacking. She'll be located at the north west base. Go all the way to her place and attack her as much as you can until she's defeated.

Impa would come out and decides to go to the Fairy Fountain. Go to her and defeat her as well. She'll come out of the south west corner so be ready to take her down until she's defeated.

Zelda's reckoning
Zelda can't take it anymore and decides to come out from the west side. Unless you want to wait for Impa to come out again, attack Zelda as quick as you can.

Admitting defeat, Zelda calls on everyone to retreat and fight another day. Cia will continue on her conquest as she'll discover more unique locations along the way.
