Faster zombies


After searching and searching console commands I founds some commands for modify zombies health, damages and stuffs like that

But the think I was really searching is a command for the zombies walk faster that normal (if you ask why, I’m playing zombie survival with toybox weapons)

If someone know a console command (or a mod) please tell me

(no comment with my spelling please, I do my best for write the most correctly and understandable possible)
