1) First extract the powder.bsp and the powder.txt file into your half-life/valve/maps folder.


2) To install the HL-Map "POWDER" you have to copy these two files from the    half-life/cstrike     directory
into your      half-life/valve     directory:

cs_office.wad
cs_bdog.wad

Otherwise this map will not run.
Moreover copy theese six files from your      half-life/cstrike/gfx/env   directory into the folder    half-life/valve/gfx/env

snowlake_bk.tga
snowlake_ft.tga
snowlake_lf.tga
snowlake_rt.tga
snowlake_up.tga
snowlake_dn.tga


I´m sorry that you have to do this but it´s the only sensible way how to use Counter-Strike textures in Half-Life.
