It's Half-Life's 20th Birthday! Feel old yet?
It seems that I've beaten valve in counting to 3 (again) xd
So a few days ago I saw this in Steath Entertainment's tweet involving Half-Life's 20th anniversary, and fell in love with the picture. So I decided to ruin it and make it as a background! :P
I'm sorry for the low quality screenshot, I can't take screenshots higher than 1280x800. But I promise it looks much better with 1920x1080 resolution ;)
Check older versions here:
