Regarding Filming and Cinematic Scenes: I have two save games for Legendary. I play my first save game first on hard difficulty. When I have completed an area I load my second save game on easy and film some cinematic shots. The cinematic shots in the beginning of the video were actually filmed last, on a map I don't destroy/alter anything on.
Texture Pack Info: The texture pack is a mix of several different packs. As it contains spoilers I won't be offering it for direct download until later in this series, but if you'd like to use any of its component parts you can google them or find them on the Minecraft Forums: All tools and weapons except for fishing rod and shears designed by myself from scratch. Armors edited by me from skins I liked from the Skindex. Textures are from The Painterly Pack with some modification by me. Mobs are mostly from NorseCraft. Ghasts are from Pixeludi. Paintings are from Sheep Craft.
Music - Agnus Dei X recorded by Kevin MacLeod | Incompetech.com Its not as good as Mussorgsky, but then nothing is, to be honest.
