So in Your configs folder are something like zombieplague.cfg , so open it and edit
Code:
// General
// -------
zp_delay 10 // Time before first zombie is chosen, in seconds (will be randomized a bit)
zp_lightning "c" // Map lighting ["a"-darkest // "z"-brightest]
zp_thunderclap 90 // Thunderclap rate in seconds [0-disable]
zp_triggered_lights 1 // Allow map triggered lights (eg. light switches)
zp_remove_doors 0 // Remove doors from maps [0-none // 1-rotating only // 2-all doors]
zp_deathmatch 3 // Deathmatch mode, respawn as: [0-disable // 1-human // 2-zombie // 3-randomly]
zp_spawn_delay 5 // Delay before respawning on deathmatch mode in seconds
zp_spawn_protection 5 // Spawn protection time for deathmatch in seconds [0-disabled]
zp_random_spawn 0 // Enable random spawning (will use CSDM spawns if present)
zp_remove_money 0 // Remove player's money
zp_zombie_classes 1 // Enable zombie classes
Is it so hard to look into .cfg?
