Planet Zoo 1.0.3 Update Patch Notes

All you zookeepers out there, rejoice. Frontier Developments has released the Planet Zoo 1.0.3 update today, November 27, and this is going to turn the elaborate zoo simulator into an even bigger and bolder game. According to the official blurb, update 1.0.3 contains more than 400 fixes and updates. While most of the changes are related to stability and performance issues, the Sandbox Mode received a wealth of new features to create an even more addictive gameplay loop.

Planet Zoo 1.0.3 Update Patch Notes

For a zoo simulator to work, some conflicting features must be added to make the game feel alive and faithful to its real-life counterpart. The Sandbox Mode saw the addition of a few of these mechanics, including death by old age. Don’t get too attached to those cute pandas, because they aren’t going to live forever.

The Sandbox Mode is getting other new options to further enhance its scope, including fence degradation, staff happiness and energy degradation, and animal welfare needs, among other things. If you want your guests to be pleased with the zoo trip, you must do your best to keep the animals happy and healthy, and the wellbeing of the staff is a part of the whole picture as well.

One curious issue that this Planet Zoo 1.0.3 update addresses is an instance where an animal could die of dehydration while swimming. If you take a second to think about it, this is the kind of bug that could put the official “ultimate zoo sim” tagline at risk. Imagine the baffled reactions from players witnessing their animals dying of thirst while they bathed in the precious tasteless, odorless, and colorless liquid.

Speaking of odorless, Frontier decided it was time to tweak the “eeuw” audio reaction to pooping. Now it’s up to you to decide if the new disgusted reaction is an improvement over the old “eeuw.” Details that truly matter.
