The Last Stronghold

From BoardGameGeek:

The forces of darkness have pushed all the way south, destroying everything in their path. The city of Lux is all that stands in their way from completely overtaking the realm. A small group of heroes must work together to fend off the evil army long enough to take out its leader. The Last Stronghold is a dice-driven siege game in which you must fend off monsters in the areas surrounding Lux and prevent them from overtaking the city. You use special abilities and magical artifacts to manipulate the dice and monsters, with the goal of eventually taking out the final boss...should you last long enough. On your turn, you add threats to the board, decide which threats you want to deal with, move to that location, roll dice and use hero abilities to get rid of those threats, and repeat until you either defeat the final boss OR all heroes are incapacitated OR the main city you're protecting takes too much damage. -description from the publisher
