This is my Halo mod. It is not completely finished, but I have it good enough for me to release it. I plan for it to have every weapon and every variant of those weapons (maybe not the Halo: 5 stuff) and I plan to add every Mjolnir type. I also plan on adding every alien and most of the worlds and structures, including the halo rings. I plan to add much more, basically everything in the halo universe. It will all be survival friendly, fairly easy to understand, and make everything look like halo while still looking like it kind of fits in Minecraft.

I also recommend the mod Armored Arms for immersion.
