If you don't want to be exposed as an alien with the overlife resource pack, well this addon makes you feel less exposed! This addon changes the interface to be red rather than purple, and makes you feel like you're undercover in a city. (a bit of overlife spoilers, sorry) You can use this resource pack as a base if you want to make your own Overlife resource pack HUD addon, too.

How to install:
just like a normal resource pack, drag the zip into your resource pack folder
put the addon at the top
boom it's supposed to work
