Take command of an 18th century European fortress and using stone walls, stout soldiers, powerful cannon and cunning traps to hold your blockhouse against waves and waves of attackers. Vauban is a fortress defence game inspired by classic tower defence games and castle defence games like Rampart. Taking command of a european fortress in the age of black powder warfare as one of three factions (Britian, Prussia or France), the player must earn funds by weathering successive onslaughts of attackers and use this money to repair and expand his fortress. Strategic placement of walls and bastions are key, as is the timing and use of traps like the Trou-de-Loup or the exploding siege mine. Master of Fortresses has two main gameplay modes. In Skirmish mode, the player can choose to construct and defend a fortress for a pre-determined number of waves on one of ten maps divided between three difficulty levels. Success in Skirmish Mode earns a player Campaign Honours, which are saved to his profile. Earning a Campaign Honour (all 54 of them!) bestows bonuses onto the player, which could mean the difference between victory and defeat. In Endless Mode, the player can test his skills against an endless and ever-increasing army of attackers until he is inevitably overwhelmed by sheer numbers.
