Also note that I used the L4D1 version of this mod to write this guide, and there may be some slight differences between it and the L4D2 version of the same mod, but it should still work well enough for both of them to get you through the main points required to complete the campaign. NOTE: This walkthrough is not for the actual Silent Hill game, it is for a player-made add-on campaign (mod) for the multiplayer zombie apocalypse games called Left 4 Dead 1 and 2.

The files for this massive and highly detailed 12-map campaign can be downloaded from, for both L4D1 and L4D2.

Many thanks to Leafo, the original author of this campaign, for creating a wonderful Silent Hill mod for my favorite zombie-shooting game series.
