A hybrid between a bunker and a ventiation structure. It has three big fans on it's roof that take the air away. No doors are present which implies that the entrance to the building is somewhere underground. This model is made as part of a big set of building used in a game I'm working on. It's extremely low poly and it comes with two 2048 x 2048 textures that represent a casual building and an old, worn off one. It has 254 polygons or 526 triangles.
