NOTE: This plugin only works in a hosted match or in offline modes. It will not work in an ordinary private match.
To open the settings, press F2, go to the "plugins" tab, and find Aimbot. There you will find settings to enable the mod, toggle which teams are helped by the aimbot, and change the strength of the aimbot.
The aimbot targets the center of the net and applies forces straight in the direction of the line from the ball to the goal. The max speed cap of the ball is determined by how hard the ball was last hit by a team that is actively being helped by the bot.
