From their post:
Nice: the Expansion continues the theme of any Genre, any scale & any miniatures. With over 50 new powers, more scenarios, more miniature bonuses, vehicle rules, civilian rules, even new ways to play!
No miniatures? No problem - The rules still allow you to have a cucumber and a croissant in a pitched battle to the death! Available in their online store (www.projectgood.co.uk/store.html) or from Wargame Miniatures' Online Store (www.wargame-miniatures.co.uk)
