Rainbow Six Vegas 2 thermal vision trailer

Today Eurogamer want to tell you about thermal vision:

"Note, this is not to be confused with thermal scanning that we told you about yesterday. Or to be confused with thermal underpants. We see thermal vision rather a lot in war games, where your enemies show up as heat signals so you can see them in low visibility areas. Watch our skilled Rainbow Six Vegas 2 killer demonstrate this in an exclusive Thermal Vision Trailer on Eurogamer TV."
