I played this long ago and was delighted to find it again on GOG. It's an atmospheric FPS with large sprawling levels. It encourages thinking and being stealthy rather than rushing in gungho with all guns blazing. The voice acting is a little "cheesy" but lends a charm to the overall game. It works perfectly on Win 10 once you tweak a couple of items in the games "game.ini" file. First of set the textures to TextureFormat1=32 0 0 0 65 0 0 0 0 0 0 0 32 0 0 0 0 0 255 0 0 255 0 0 255 0 0 0 0 0 0 255 TextureFormat2=32 0 0 0 65 0 0 0 0 0 0 0 32 0 0 0 0 0 255 0 0 255 0 0 255 0 0 0 0 0 0 255 you can also set "NoFog=1" to increase the view distance. Next, delete (or better still rename) winmm.dll to winmm.dll_OLD That's it! Enjoy! :-)
