Okay, I admit it. I’m a huge Half-Life 2 fan. I think Valve’s games are the best, most intelligent and immersive games. The worlds they create feel very real. I’m looking forward to the next chapter in the series. This is my own fan-based image, created from photos I took in one of the bleaker parts of the city. I combined them in Photoshop with various elements from screenshots, including a shot of one of my own prop guns. This character is obviously in a bad spot, with a train bearing down on him and two striders on the way. He’d better run…
