Get ready for the ultimate hardcore adventure with 'Insomnia: Hardcore'! Experience a new level of immersion and exploration with enhanced world generation, improved combat and new dungeons to conquer. With a unique revival system in place, your hardcore journey doesn't have to end prematurely just because one player in the group dies. Discover new content and mechanics that adds depth to the game, all while not straying too far from the classic 'vanilla' feel of Minecraft.

-[ Revive System! 🩺 ]-

Say goodbye to respawning, in this modpack you rely on your friends to revive you after being taken down. It's therefore all about teamwork and punishing careless play! (But not too much). To revive a fallen ally you must apply a 'Potion of Revivify' to the victims corpse.

Increased mob spawning at night!

-[ Origins and Classes! 🦍 ]-

As you enter a new world, get ready for an important decision: choosing your Origin and Class. Each option comes with its own set of fun quirks, buffs, and debuffs. So take your time and weigh your options carefully before embarking on your exciting adventure.
