Gravity Zones
No, not anti-gravity zones- gravity zones.
Place them wherever, and get gravity once you enter them.
Useful for maps with an earth and space- earth can be covered in gravity zones, space can just have an anti-gravity script.
Reliable Anti-Gravity
A script, not a zone. Should somehow work with the gravity zones, if possible. If impossible, don't add compatibility with gravity zones, just please make the add-on.
I'm not sure if there's a download for this, but a reliable anti-gravity add-on, including:
-On/off toggle
-Some way to easily propel yourself in zero-g
-Some way to propel downwards
