hello, I suggest to increase damage of chainsaw:
1- this weapon is expensive and few of players using it just for healing themselfs.
2- weapon is effective to be used only on afk players( at least 5 times to kill afk zombie), there is no chance to kill a zombie with.
3- it's gravity is high, zombies can get you fast so it's impossible to escape with.
Additionally zombie can use madness against him.
Thanks for your time😊
