The 2011 edition includes a new duel variant for two players. Additional material are 6 cardboard tokens and a duel score track (printed on the back of one of the scroeboards).
There is an inset on the box front saying "NEU! Jetzt mit spannender Duell-Variante". Also there are more awards printed on the box (MinD, spiel gut, Spiel der Spiele).
