- Actions – such as planting explosives, hacking into a databank, or performing a ritual – and how they can be performed (and in some cases, prevented)
- Rules for terrain features, such as Hills, Obstacles, Area Terrain and Buildings, including traits the terrain might have and its impact on the battlefield
- Hints and tips for setting up a suitable battlefield, in terms of density and type of terrain, type of terrain, and ensuring that neither side of the battlefield is preferential to the other
