    It's most easily noticed by using the flashlight.  It seemed that most
of all the surfaces in the game have a bumpmap on them... some even seem to
have a solid colored texture with a very elaborate bump on them.  Check the
walls and floors of the space ships ( that teal floor on the alien ships is
a good one )... wave the flashlight around.  Especially check out the ground
in the snow covered areas... they use bumpmaps to give the low poly ground
some really nice snowy detail.  Looking at their dynamic lighting and
bumpmapping i found a hallway in the final space ship map that had some
screwed up normals.  They do seem to have very low geometric detail in the
world... it's all in the texturing.  =)  Tom
