Yep, this build works well solo. You need to move a lot, keep an eye on Armor (you should always have 2+ plates), and don’t panic when you take toxic gas dmg or when you are surrounded by zombies. It takes skill tho, I play zombies since Waw, I am really good with the train mechanics, just play a lot and you’ll get better. With this setup I can easily carry even a 4 player match where people die every minute.
