Kept you waiting, huh?

A promise is a promise. Today is a one year anniversary since I took over this awesome campaign. I want to thank everyone for all the supportive comments, achieving 5 Stars on this campaign and for playing this version in general. Specials thanks to Goo Ball for reporting most of these issues. Had it not been for him, this update would have been much less ambitious and retain all the many cheesy strats that are no longer possible. And Roku, for helping me out with stuff, that I could not sort out on my own. Here's a long list of changes done in the update:

General:
- Changed keys and doors mechanics: the doors locked from the other side are now actually have to be unlocked from the other side. Picking up the keys will not immediately unlock the doors. Instead, approach the door and press USE to use the key. If you got hints enabled, you'll be informed about successfully using the key or unlocking the door. Enabling the in-game instructor is now strongly recommended for a better response on your progress.
- Same goes for quest items: you'll be informed about picking up or using one.
- The locked doors are now unbreakable until unlocked
- Arranged infected populations: the main infected type is default L4D1 infected, which will spawn in the Fog World. The L4D2 infected will appear in the Otherworld. (both Commons and Specials) You will also encounter various uncommon infected in relevant locations from now on.
- Arranged Witch types. You will encounter walking Witches during Day Time and well-lit areas in general.(excluding Bride in the Church) and sitting witches during the Night and in dark areas (like sewers).
- Added rusty weapon skins. You will find alt weapon skins in the Otherworld chapters and default weapon skins in the fog world
- Added more hints about puzzles as well as more hints in general to increase interaction with the world.
- Added more sound effects from the original game.

- Converted some props from dynamic to static
- Prevented boss spawns inside Levin St. House
