RWUCraft

This is a lite 1.12.2 modpack (Less than 100 mods), runnable with only 3gb RAM allocation.

Despite it’s smaller size, this modpack contains a whole lot of fun, with way too many mobs to count, things to explore, villages to conquer/build, and technology to master as you progress from your stone tools to power suits, godly weapons, guns, spaceships, and more.

A quick method for getting started: Cut trees for some wooden tools such a pic-axe, shield, and throwing spears. Mine stone for a stone tool upgrade. Look for structures that may contain routes into dungeons. Slay zombies and other mobs for gear and loot. Acquire some decent gear and start building up a base or village, utilizing various forms of technology. Protect it with golems/mob pets, guards, and more. Build up your power suit and  launch base. If you can even make it this far, travel to the galaxies and beyond for further adventures!
