Insurgent - Black Ops Profession
This mod allows you to start as a highly trained black-operations operative, known only to a select few as the "Insurgents", sent into the Knox Event's Exclusion Zone for a highly classified mission.
Sun Sensitive Zombies
Another take on Night/Day zombies! One of my nit picks with the night/day mods I've tried thus far, is the timing of the lore shift from day to night isn't always accurate year-round. Sometimes the zeds will start sprinting hours before or sometimes even hours after it gets dark!
