Before you install, Greasy Fork would like you to know that this script contains antifeatures, which are things there for the script author's benefit, rather than yours.
This script will inject ads on the sites you visit.
Locks the aim to the nearest player to your cursor. Let's you see inside buildings. That's called the X-Ray. Also shows a line between you and players nearby. The player targetted by the aimbot has a red outline. Doesn't auto-shoot, you have to shoot yourself. Could also aim at your teammates if your cursor is near them.
NOTE: Everything is enabled by default.
