Brutalmania.io is too much for mere mortals to handle! As an evolved species we often think of ourselves as being too sophisticated and civilized to partake in the utter violence and depravity of our cave dwelling ancestors but that just isn't true. Brutalmania.io is the only free casual game online that knows who you really are and what you really want. In Brutalmania.io you'll be able to customize your very own neanderthal, grab a custom club and start swinging! The competition will be brutal at first --of course it would-- but eventually you will be able to grind your way up the ladder and unlock more pwerful weapons, customize your avatar with cool outfits and even build yourself some nifty dino armor --just like our forebearers did. So swing, smash, and destroy the competition. That leaderboard isn't going to climb itself! You'll have to do like Drizzy and start at the bottom, take your knuckles off the ground, wrap em around some discarded dinosaur bones and swing away! The whole world is an arena and it is ripe for the smashing, just waiting for an ambitious young caveperson like yourself to bash it in and pull it inside out.
Brutalmania.io operates much the same as many other free online games. For example, you move your character with the aid of the W,A,S,D or the arrow keys and you make your attacks by pressing the left mouse button.
