(adsbygoogle = window.adsbygoogle || []).push({}); I need help with finding offsets

EXAMPLE:
Black ops 2: VSAT, Red Hexagon
Modern Warfare 3:Advanced UAV, Red Boxes
Basically Non-Host Offsets

IM NOT SAYING I WANT TO FIND THESE OFFSETS

I want to know how you would find them and how you would enable them
What would I need?
What would I need to search for?

sorry if this is the wrong section
