SC: Swampylands

This light-weight pack focuses mostly on the mod "The Betweenlands", a very unique dimension on its own.
There is no overworld, you will spawn inside the betweenlands and stay in it the entire time.

Features:

• Several Quality of Life mods to improve your time inside this swampy world, such as more informative stats and HUD icons; as well as some performance enhancing mods like Optifine. 
• Betweenlands style redstone.
• Light-weight - while the betweenlands itself can be a bit on the heavier side, the pack has several performance mods as well as a low mod count to help with that.
• Betweenlands-styled Texture Packs to enhance the swampy look and feel.
• Client-to-Client hosting powered by the Essentials mod; so you can play with your friends without a server!

Recommended 4GB RAM.

While you can use Optifine, set "Fast Render" to OFF to avoid rendering issues.
