About Heroscape: Roads of Valhalla Terrain Expansion, from BoardGameGeek:
Much of Valhalla's infrastructure has crumbled over the past decade of unending conflict. While monuments and works of art have long since collapsed, the Valkyrie generals still maintain a network of old stone roads and bridges to keep their armies supplied-for in Valhalla, all roads lead to WAR.
Add speed and strategy to your battlefield maps! Includes road terrain tiles that boost movement and short walls that attach to create custom bridges–perfect for controlling the flow of battle and building epic new maps. This terrain expansion is fully compatible with all Heroscape terrain. Mix and match this expansion with any terrain for seamless integration into your collection.
This is add-on content. A Battle Box and/or Master Set is required for Heroscape gameplay
Moving on Road Spaces: When moving your figures on road spaces, count each space as a normal space. However, if your figure's entire move consists of road spaces, including the starting space, you may add an additional 3 spaces to your figure's move. The 3 additional spaces must also be on road spaces.
Short Stone Walls rules: They are height 3, with the inside having a height of 2 and the outside having a height of 3. Figures can climb over stone walls, but it requires sufficient movement and height. They also block line of sight. The Walls also have Line of Sight marks for tracing from behind the wall.
Laur Walls Rules: Walls block Line of Sight, Clear Sight, and Movement for some characters.
