In "Thunderstone: Heart of Doom", you had a chance to face Doom's very heart, the eighth Thunderstone, and defeat the ancient evil – but winning that battle had unexpected consequences. It banished Doom, but also freed him to visit other worlds, so you advanced to the next world with him. Thunderstone Advance: Towers of Ruin, which is fully compatible with all previous Thunderstone offerings, is the next stop in your adventure. In Thunderstone Advance you build your party of heroes to defeat the dreaded Thunderstone Bearers in their dungeons or wilderness. The player who defeats the most valuable monsters will win the day, but beware – those monsters have all-new tricks up their sleeves, and victory will not come easy.
