When trying to upload Shad0wolf0's Survival+ v1.0 Release, I was informed that Sodium, Iris, and Mod Menu are not on CurseForge anymore (the pages are still there, but the files aren't). I was excited to get this release out but unfortunatley due to the modpack for being rejected for having these files while they do not, I cannot upload this to CurseForge anymore. Updated versions will be available on Modrinth!

Immersive Survival [1.20.1 update coming soon]

Immersive Survival is a vanilla+ pack that provides a unique experience using ambient and immersive cosmetics, effects, and sounds. The modpack is survival multiplayer friendly so it can be used on your friends Vanilla servers or on many servers that you choose (use at your own risk).

This pack is probably heavy to run! You might expect bugs or performance issues!
