I saw the 40 meg patch and was like ooooooooooooooooh yeah new textures and maybe sounds!
/edit: any place in particular that we have to see?
/edit2: just running through p1 is enough to get a stiffy.
/edit3: with the surrounding texture around entryways like sewers and such makes me very very hopeful for the 'primetime' textures that are so heavily used - floor, wall, ground... all of it. Very nice work in what I have seen in the last 5 minutes.
