Silent Hill:The Pledge is a fan game based on the Downpour universe and tells the story of the postman (Howard). The game plays much like SH:Downpour. This is our own version of what happened to the postman and how he got into SH and hopefully it'll fit with what the writers might have had in mind for him. A demo version is already available
Here is the demo (first stage), it's 250 MB in size and you'll have to download all the 3 parts to launch installation. Just make sure you have a descent graphic card (with shader model 3 support) to be able to play this, if SH:Homecoming played fine on your PC then this game will run just as fine for you.
