ZRP (means zone reclamation project) is a general mod which tries to fix and improve the original game, like an unofficial patch, but without drastic changes to the gameplay. Weather overhaul is a nice weather and mood lightning modification, and includes the sharper textures mod and the float shaders mod. Are there any must-have mods that are compatible with the Steam version? Hey guys, I’m going to pick this game up in the next couple of days off of Steam.
