Heroscape Master Set: Swarm of the Marro - 2007 - Milton Bradley - Great Condition
There are 2 large ruins and 85 tiles of terrain in the base game. Some terrain tiles are large (up to 24 hexes) while others are small (1 hex). There are water, sand, rock and grass tiles (in roughly increasing order). Many different battlefields can be built by attaching and stacking the tiles.
The rulebook features two games: a basic and a master version. In the basic version (designed for younger players < 8 years), characters move, attack, defend, and have range -- but there are no special powers and some other rules are minimized and/or eliminated. The master game includes special powers, wounds, engagement rules, falling rules, and a few other additions.
A battlefield/scenario book shows how to build five battlefields, layer by layer. Each battlefield may have multiple scenarios, where the goals vary. It can be opponent elimination, getting to a certain space, protecting a certain figure, or holding out for a certain number of turns.
Each unit in the Master Set has a movement rating ranging from 4 to 8, which is the number of hexes it can move in a turn. Moving up a level counts as a hex; moving down does not incur that penalty. Moving down more levels than your height when moving from one hex to another counts as falling and you might take damage --unless you are falling into water.
Combat in the game is fairly straightforward. You roll attack dice as listed on your unit's card (1 to 8 dice in the Master Set), and the opponent rolls defense dice equal to the number on their unit's card (1 to 9 dice). Skulls rolled in excess of shields count as wounds (hero figures may have more than one Life).
The master game uses a point system in which players alternate drafting cards until they reach the pre-assigned point value for the scenario. It's possible to bring a "pre-fab" army to the battle in order to save time.
