So, nothing really special here, just more dice for your Star Wars: Imperial Assault adventures.  While these extra dice are not necessary for the game, it is really nice to have them, especially when playing the campaign game when there is up to five players.  Instead of scrambling and searching for the dice each time you activate and attack, you'll be much more likely to have some nearby.  It's not a huge deal, but it is really nice.  Short story, this dice pack makes a great game even better.
