The R63 virus is a terrible one, you hear screams and you were a survivor, you had a gun, spike bats, and shotguns and a backpack, You hear screams and multiple shooting sounds, it could be other survivors fighting the virus but…you hear screams and people screaming and it stopped meaning…not a good thing, you heard footsteps, was it a R63? Or, was it just your imagination. Survive as long as you can, and find other survivors or, go alone A lot of R63”s can be heard running and infected people
