Hey, I'm stuck at the chapter 18? The one in the church because I don't know how to use the keys. Do I have to manually kill an enemy instead of nuking them for it to work or there's another way?
You need to manually kill them or buy keys from the store. Then you stand next to a door with a key and you can open it.
Nuking enemies puts their keys in the convoy, meaning only units next to the MC can access them.
