    Worth to try, but need patiently

    So, this campaign is one of the custom campaigns The 5th Survivor added to his non-steam servers in 2020?

I know this campaign was made by 5 other people, but the difficulties are uneven. The 2 first maps were hard and took long to finish, while the 3rd was short and easy. The most challenging map was the 1st but it was starting without guns or supplies. The 4th map is the my most favorite cuz of it's asmotsphere and design,but it's also the map where bots stucked the most. The last was less amazing. The campaign generally is pretty good.
