need help finding a cool concept art picture

[jedibob666]

so i was surfing as usual and i came across a pic form half life 2 on 4chan.org

it seemed new and it was a profile shot of combine soldiers in the dark in a line marching with the half life logo glowing on one of the soldiers in the middles arm

for some reason i cant find it anywhere and its gone on that particular forum

does anyone have it or can they point me in the general direction?

thanks
