Once your download is complete, click Extract To and extract all 7 Battles to My Documents/My Games/Age of Mythology/Savegame (Unless you moved it)
Once all 7 battles are in, go into Age of Mythology game, click single player, and click Recorded Games. Now you should see the 7 Tw battles. Just double click and watch em' all. Hope you enjoy the pack.
File submitted is Tw Battle 7, I had to pop that in so I could submit the post.
