Did you know that some time from 2006 to 2007, Arkane Studio, the developers behind Prey and Dishonored were working on the new Half-Life game? Dubbed as Return to Ravenholm, or Half-Life 2 Episode 4, the game took place in the European town of Ravenholm and was said to feature a story told by a new character perspective. The title obviously never took off, and since its a cancellation we have a few screenshots to see what the title had looked like. Well now we get our first real look at some actual gameplay footage.
