Killer.io is a multiplayer killer simulator that you can play here on pbs jocuri online. You will appear at a wild Halloween party and your task will be to kill as many people as possible. But you have to do it so that nobody notices it. You can then throw the body into the trash can, which is in front of the house. If somebody will notice, they'll call the police and they'll take you away. You can join again later, but you will lose valuable time that your opponents can use. For the coins you can buy a new costume for your character in the menu, so try to finish as high as possible in the scoreboard.
