Updated content includes:
Smaller Outdoor Levels - The first outdoor area has been separated from the larger, secondary area. This makes that area run a lot smoother than before, and should not impact your frame rate as much.
I plan to split up the second area too, since it is larger than the first area, then the game will have three, similarly sized outdoor areas.
Outdoor Plants - The plants that appear on the outside terrain had a problem that caused them to not appear in large stripes when moving across the map. This has been addressed, and now plant coverage should be more uniform.
Outdoor Sounds - This was actually in the last update, but I forgot to mention it. The outside areas now have a different ambient noise, and different footstep sounds to match the more natural environment.
