Just uploading some screenshots of my old levels as archival, this one was originally made for a zombie survival gamemode in Garrys mod.
Originally
Set in a power station, built into the side of a cliff, inhabitants have taken refuge from the zombie outbreak in it, unfortunately as with time, it has seen an attack too, and now must be defended!
Props/textures used is from Half-Life 2, all level design done by me.
