Box Styles are Full or Corner. Skeleton draws a bone overlay. Head Circle marks the head. These are appearance options on player ESP. They do not add new targeting.

Choosing a style

Corner boxes occupy less of the sky in aerial fights. Full boxes are easier to track through terrain. Skeleton helps with facing and animation; it is noisier at long range. Head circle is redundant if you already use Head bone selection on aim assist.

Colors

Line color is a customization setting, including visible versus hidden colors. Do not treat color choice as stealth.
