After seeing Planet Zoo 2 gameplay behind closed doors, I've often thought about its sag mechanics. It's a word that made the developers at Frontier laugh and wince at the same time, chuckling that they really couldn't call it that at launch. But, despite the connotations, it really does play a key part in one of the big new additions for Planet Zoo 2 - the aviaries.
These huge new habitats are built on the enclosure mechanics from the original game, but with a key difference being canopies that you can craft as roofs to keep your new feathered pals safely within. Made from essentially gigantic nets, you're given full free-reign to position poles wherever you want around the enclosure to hold the net aloft or adjust the way they're rotated or tilted. Which brings me to that all-important sag mechanic - aka, how the net drapes or sags between poles. You can swap out the canopies for glass or other materials, too. The effect is pretty cool, especially when you realize these new enclosures are completely explorable on foot by your guests.
