Highrise was a prototype exploring what happens when the primary combat space is vertical urban density — multi-story building interiors, external fire escapes, and rooftop geometry replacing the ground-level street layouts that dominated the launch maps.
The core design question was whether Spectre placement could meaningfully work across floor levels within the same building — using one body to hold a stairwell while the other covered a window on the floor above. This created novel read scenarios genuinely different from the horizontal bi-location patterns established by the launch pool.
The prototype also tested how attackers navigate vertical approach geometry when both bomb sites exist at different elevations within the same structure.
