New York Episode 1 Extinction Solo without bots - World War Z Aftermath (Pre Walking Dead update)

I play mostly as Hellraiser class in World War Z game and I am challenging myself to complete all campaign maps on Extinction difficulty as a solo player without the help of bots or human players. This is my run on New York Episode 1. I completed my solo Extinction without bots or human players challenge on all maps on Xmas day (25/12/2025) just when the Walking Dead DLC and update was announced. I guess I have to redo my challenges again once the new update with the spiked special zombie drops. #wwzaftermath #wwz #worldwarzthegame #worldwarzlive
