I recently beat the Splinter Cell sequel "Pandora Tomorrow". Very fun game. Anyway, this is my first attempt at an ID. Firstly I have to give credit to the makers of the original wallpaper that I took the image from (forgive me, my skills aren't so great that I can casually create my own Sam Fisher scene). The golden particles are the contents of a Chaff Grenade, a grenade that explodes and emits particles that disrupt electrical equipment for a short while.
Lemme know what you think, I hope you like it.
