Probable Future Asked Questions:

Q: Actually functioning Thermal Scope?
A: Trust me, I wanted to make the thermal sight, since it's easily the most unique of the MW2 scopes in terms of function. However, last I checked of Alcat's Thermal Scope/Cpone's thermal highlighting code, it would cause horrible horrible lighting/material issues.
