Mars mod!!!
Mars mod!!! adds a Mars dimension with two bosses, its own structures, several enemy types and items crafted from boss drops.
What it does
The Mars dimension is reached through the mod and is built for exploration. Each world area has its own structures and a set of enemies, and two bosses guard the progression, with lore told along the way. Players who want more than the standard exploration of other space mods get a dedicated side plot with a boss fight at its core.
Two items can be crafted from boss drops, and the author describes them as useful for adventure play. Servers that run it need every player to install it too. It is published for NeoForge only, with files for 1.21.4, 1.21.5, 1.21.6 and 1.21.7, and it is not open source; it is released under All rights reserved.
