Killmonster is the simplest browser based game possible. It simply lets users fight monsters in a 1-click battle. Monsters are created by the administrator and battles are weight by the user’s skill points and the monster’s skill points. New feature in 1.2 lets users fight each others. AN optional PM block is available here but it not included in default installation.
