Version 2.1:

The original campaign, version 1.0, was released December 17, 2013 on GameMaps. Before uploading it to the L4D2 Workshop, the campaign has been overhauled with the following changes:

- Added new pathways to each map
- Many areas that looked accessible but weren't are now accessible
- Many areas that looked accessible but weren't are now visually blocked
- Updated lighting throughout each map to be more unique and appealing
- Added more general weapon spawns
- Added more general item spawns
- Added unique weapon and item spawns hidden throughout each map
- Added more rescue closets
- Improved bot navigation
- Common infected now use specific populations
- Defined boss spawning locations

The map has been improved significantly since the first release so if you downloaded the original Version, I would recommend deleting Version 1.0 and revisiting with Version 2.1, which is available on both websites. Thank you and enjoy!
