Controlling the Undead
You could always go a different route, where instead of outfitting yourself to be more capable, you modify the zombie apocalypse to make it easier to handle. With the codes below, you toggle zombie health, turn off rushing mobs, or get rid of zombies altogether. You can also spawn additional zombies and special infected if you're looking for more of a challenge.
z_spawn mob - This will spawn a zombie horde
z_spawn (special infected) - Enter tank, smoker, hunter, or boomer in the brackets to spawn that special infected in your crosshairs
z_health - Allows you to toggle zombie health
z_common_limit - This sets the maximum amount of regular zombies
director_force_panic - Sets off a panic event, in which zombies rush you
z_speed - Toggle zombie speed
z_spawn zombie - Spawn a single zombie
tongue_range (#) - Put in a number to set the smoker's tongue attack range. Default is 750.
director_stop - Turns off all wondering and rushing zombies, as well as specials and bosses
director_no_mobs (1/0) - Turns off mob rushes
