Anyone know how I can do this?

I managed to edit the health using
Edited [~20 Hits]

zombie_utility::set_zombie_var( "player_base_health", 				999 );

That one was a lot of hits.

Base [3 Hits]
[code[zombie_utility::set_zombie_var( "player_base_health",             100 );[/code]

So I'd guess around

zombie_utility::set_zombie_var( "player_base_health", 				77 );

Not sure though
