Chapter 2:
- Complete overhaul and advanced optimization: a large portion of the map has been rebuilt to match source engine optimization standards. Visually and gameplay-wise, there will be no changes. This has been done, because the map was horribly optimized and would take ages to compile. There should also be insignificant improvement in frame rates. However, some things were broken and I had to fix them manually. Do report, if you find something that I may have missed.
- Added a few infected ladders, where specials could spawn, but couldn't get out of there.
- Fixed item transition from previous chapter
- Added weapon spawns in the starting area, which will appear, if you start a new game from this chapter (not otherwise)
- Blocked off cheesy spot near the trap in the alley.
- Added hints on what you need to do in school.

Chapter 5:
- Fixed item transition from previous chapter
- Added weapon spawns in the starting area, which will appear, if you start a new game from this chapter (not otherwise)

Chapter 6:

Chapter 12 (ending 1):
- Added navblocker to finale door

Chapter 13 (ending 2):
- Sealed off a door in hospital section that would show the void
- Fixed missing hospital section music.

Still putting off the removal of occluders on the first map, since it will require as much effort as I've put into the second map on which I've focused primarily during the making of this update. The item transitioning will be fixed for all chapters eventually, but will take some time, stay tuned.

General:

- Adjusted music settings. They should guide you, when you approach the area containing the keys or quest items that will help you to progress.
