Incredible behind the scenes presentation of an official map, and the most creatively innovative of the 5 accepted Zombie Infection maps in my opinion. The included vmf is a wonderful learning tool, seeing how instances were used for off-kilter buildings was a pleasant sight.
The swamp assets are also very welcome given it's a rare environment theme with previously a small selection to use for. I personally learned you can place light_environment entities inside instances to allow Hammer++ to bake lighting inside them for a no-compromise lighting preview (just have to bake them all individually). The reed cluster and swamp treeline brush is worth celebrating for.
The included ZI assets feel unnecessary since I already had them, and I had to carefully pluck them out to not conflict with existing files. I'd personally prefer it as a separate download, but regardless, the pack has a professional aura around it. The effort and work put in shows and I'm sure it will inspire people and maps alike in the future.
