5.1 All rules regarding Printed Rubble (O3) are in effect (EX: hex FF27).
5.2 PARTIALLY COLLAPSED BUILDING:7 Any Printed Rubble hex that contains black-bar artwork is a Partially Collapsed Building hex, representing a building that is Rubbled but has portions of its walls still intact. Except as otherwise noted, a Partially Collapsed Building hex is treated as a normal Rubble location (B24; O3).
5.21 OBSTACLE HEIGHT: A Partially Collapsed Building hex is a normal Half-level obstacle Rubble hex with the exception of the wall depiction itself (represented by the black-bar artwork). The height of the wall depiction is determined by the hex center-dot.
5.211 LEVEL 1 OBSTACLE: A wall in a Partially Collapsed Building hex that has a regular center-dot (EX: hex P24) rises to a height of 1 level.
5.212 LEVEL 1.5 OBSTACLE: A wall in a Partially Collapsed Building hex that has a large white center-dot (EX: hex Q25) rises to a height of 1.5 levels.
5.3 COLLAPSE: A wall in a Partially Collapsed Building hex will collapse from any result that would normally create Rubble (B24.11) in a building Location; Falling Rubble (B24.12) is NA (for the effects on any occupants see B24.11 and B24.121). A Partially Collapsed Building hex in which the wall collapses is marked with a Rubble counter of that building type, and thereafter is considered to be a normal (Half-level obstacle) Rubble location.
