Started a new game and the Leader of the Pack achievement popped for me. Not sure how but I'll take it!
Started a new map just for the update. Great world, lots of cool scenery but the nether is horrible. Had to blast away with TNT for almost an hour just to find a cavern larger than 5x5. Even then, the one I found was 1/3 of what I had created to find it.
I need to own this.
Left 4 dead 2 mod. Deathcraft 2.
It has been updated since this vid, all the weapons and items have been 'Minecraftized."
