To play Warhammer, you do not necessarily require any specific terrain pieces, as you can play the game using a flat surface or a gaming mat. However, the use of terrain can greatly enhance the game experience and add a level of realism and immersion to the game.
Games Workshop recommends using a mix of terrain types, such as ruins, forests, barricades, hills, and buildings, to create a varied and interesting gaming environment. The specific terrain pieces required may vary depending on the type of game being played and the size of the gaming table.
For example, a small skirmish game may only require a few pieces of terrain, such as a building and a couple of barricades, while a larger battle may require a mix of terrain pieces, such as hills, forests, ruins, and buildings, to provide cover and strategic opportunities for both players.
Overall, while there is no specific terrain required to play Warhammer, the use of terrain can greatly enhance the game experience and is recommended by Games Workshop. Players can choose to purchase Games Workshop's terrain pieces or create their own using a variety of materials, such as foam, cardboard, and modeling clay.
