Halo RPG (DnD-Like)

I’ve spent the last couple of weeks working on creating a Halo based Table-Top game. Like Halo DnD or something. I’ve never participated in a DnD campaign, but I’ve done some research and have a couple of people who are DnD regulars helping me along. I just thought I would share the idea, maybe get some feedback, or even have some more ideas thrown my way. Anything works.
