Instrucciones:
I launched XCOM on XP.
1. Download crack for Torchlight 2 or get steam_api.dll and
steam_rld.ini from that game (you need only working steam_api.dll, but
torchlight 2 crack works only with steam_rld.ini. possibly other game's
cracks will work, but not sure) (OS MANDO LO ARCHIVOS DIRECTAMENTE)
2. Copy and overwrite steam_api.dll and steam_rld.ini to \Binaries\Win32
(Ahora lo "pesado")
You see, the game is using some file functions that are only available
on Vista or later. This is the only thing that is preventing the game
from running, amusingly enough. There is an API from MS itself that will
allow these functions on XP, but it has not been implemented in the
game... Os mando el link porque tiene links al archivo zernel32.dll necesario.

4. Play
PS if game crashes on starting new game, go to \XComGame\Movies and
rename CIN_Intro_Movie_LOC.bik and 1080_CIN_Intro_Movie_LOC.bik or make
dummy files with this names.
A mi me ha ido de momento,
Suerte!
