I know the name doesn't make much sense but this blend basically contains props like pipes air vents light etc.
I have just put them together to show what I mean by 'Pipe Hallway'
The entire blend has only 28k vertices which is more or less based on opinion.
I really had the hallway from Call of Duty Modern Warfare 4 : Mission 2.
But no reference was used from it.
The model is Untextured as you can see in the render
Looks GREAT :D i would texture it but i don't want version 2.64 :P but other wise it would look sick textured
Looks cool, probably it could look better with textures on it, but what I'll add to it some kind of scrap on the floor, water under the floor and more details on the walls. The structure looks awesome.
