📦 About

I made this modpack for players to install minecraft Unstable Simulator more easily — without the tedious process of installing maps, selecting mods, and configuring everything manually.

All the necessary mods for PvP are pre-installed with Auto Updating Simulators.

Check out my Mod Version of Unstable Simulators "Under Review"

🔀 Version Differences

Version	Simulator Type
1.21.11-x	Carpet-based simulators
Vex-1.21.11-x	Vexbot-based simulators

---

Vexbot Simulators (Vex-1.21.11-x)

From Vex-1.21.11-7.x maps will not be included in the Modpack.

Instead there will be a button Import Simulators at the world select screen.

It might take a while due to the maps total sizes (few Gigabytes), so if U don't have time or whatever you can just use Vex-1.21.11-6.2 instead

Note: Vex-1.21.11-6.x will not be updated due to Modrinth Max File Limit (~500MB)

So please Press Import Simulators at the world select screen

Also you DON'T need to update the modpack to get the new simulators just repress the Import Simulators and Import Kits button since Vex-1.21.11-7.3
