Here’s a little movie/collection of all the cutscenes in Halo CE Anniversary without the soundtrack. Just sound effects and dialogue. It’s not quite as detailed as Halo 3, but still very interesting. Here’s the link to the video:

I’ll be working on Halo 2, Halo 3: ODST, and Reach next for this and eventually classic mode for Halo 1. In the meantime, enjoy!
