Have you ever wanted to play Halo 3 in 3rd person and play as an UNSC Marine?
You can check out a video I made reviewing two mods working together, one made by FunnyAnyways and another by RubyofBlue.
These mods add new enemy encounters, increased weapon damage, and the ability to play in 3rd person and as a Marine.
The YouTube video link is here: Playing Halo In 3rd Person and As A Marine - YouTube
The two mods will be found safely downloadable on the Nexus mods website.
