When you don't have a proper weapon and need to fight those pesky zombies, your only choice is to fight with your bare hands... and feet. You can only damage zombies using unarmed combat, but in MMA (mixed martial arts) you must use these methods of combat to kill other players.
|E||8||Punch||15 HP and push|
|Q||30||Kick||30 HP, push and trip|
Unarmed combat is only useful if you don't have a melee weapon on you, but it's still not recommended unless you're really poor and have to deal with the tinpot because it deals no damage.
