Michi has scratchbuilt the missing crossing section for one of the ten scenario layouts of Aliens versus Predator: The hunt begins. The cardboard floorplans which came with the game were replaced by 3D sections made of lasercut plywood (Bug hunt corridors kits by now defunct Fantasy Arc from 2014).
Games Workshop made plastic floor tiles for Necromunda which Michi used to turn into airducts for the AvP game. Now Boneshop offers similarly designed lasercut MDF kits to build matching floor tiles with variable surfaces. Michi bought a set and converted it into a square room with a floor grating of Fenris "Sulaco" floor cut into shape.
The walls were painted with the same Revell 55 whitish green that was used for the scratchbuilt plastic airducts, although the weathering was much more intense this time to display a really worn machinery section. Entrances are magnetized and cut to size to match the Bug hunt corridors sections.
