Minecraft Java Edition is one of the few games that allows players to install any kind of mod and use it in the game.

Although Minecraft certainly has its own physics engine built within Java and Bedrock's codebase, some players might like to see a substantial improvement to the engine.

On the left-hand side of the launcher, choose Minecraft: Java Edition. You see the Play button? To the left is a drop-down menu, which now has the Essential Mod as a launch option.
