Karnage.io is a 2D multiplayer cannon battling wargame. It is the one of the best if not the best IO shooter games you’ll be exposed to in the internet. The graphics are astoundingly pleasant, the concept of the game is not too difficult and the best part of this game that others lack is the arsenal selection that’ll drop your jaw to the ground. There’s not much of a limit as to how many players can play at the same time period, so there’s always somebody wanting to shoot and kill you which means you won’t get bored and commit suicide.
