There's not much hope in the Wasteland for anyone in Mad Max but poor Half-Life 3 definitely never had a shot. Yup, in these images from Swagmastavondagmasta (yes, seriously) on Imgur we can see what looks like a very charred Gordon Freeman, complete with glasses and a very dismembered arm clutching a crowbar.
Just in case that was all too subtle, there's even the number 3 emblazoned on the side of a crate. Thanks Avalanche. If you'd like to pay your respects you can see the location in the gallery above.
