Battlefield Set-up
RAW ✔️ Necromunda: Hive Secundus Rulebook, p121
Some scenarios will have special instructions on how to set up the battlefield; the default methods are as follows:
Underhive
The battlefields of the underhive vary vastly, from complexes of cramped tunnels, raucous marketplaces, rogue factoria and foundries, to gang strongholds and even bustling settlements. The thing they all have in common though is they are fully enclosed, protected from the unpredictable and harsh weather of the wastes.
When creating an Underhive battlefield, the default is that the ceiling is high up above the ground and so walls can be climbed up onto and stairs and ladders used. However if both players agree, the claustrophobic confines of tunnel battles can be recreated by stating that the ceiling is at the height of one wall section, meaning walls cannot be climbed over, and stairs and ladders can not be used.
For Underhive battles, between a 3'x3' and a 4'x4' battlefield is ideal, although larger and smaller battlefields are also possible! Starting with the defender (or the winner of a roll-off if the scenario does not specify a defender), players alternate placing terrain features upon the battlefield. Once one player passes, then the other player may place one more piece of terrain. Alternatively, if using Zone Mortalis Tiles players alternate placing the tiles on the battlefield.
Then, starting with the defender again, players alternate placing obstacles (see page 42) and other small terrain features. Once one player passes, the other player may place one more terrain feature.
