Halo has always been better and you all know it :D
Just kidding, well I'm not kidding but that's still beside the point. This is a great piece of art to go with a semi-great game. I love the gritty details on the zombie's arms, also I'm supposing this is black mesa, because of that Sector 5 thing on the wall as well as the simple fact that this looks nothing like Ravenholme. Anyway, great job, love this picture! Keep at it!
