Acabo de recordar que desde hace unos años ATI y NVIDIA tienen un acuerdo con Steam , un acuerdo poco publicitado , por el cual a cualquier poseedor de un grafica de cualquiera de las dos marcas le regalan el HL2 Deathmatch y alguna cosa mas . Para conseguirlo no teneis mas que usar los enlaces que os pongo .

Lo bueno de tener gratis el HL2 Deathmatch es que con eso tendreis el motor grafico Source , y con ese motor podreis jugar tambien a una serie de mods que pongo mas abajo . Para encontrar los mods en Steam usad el buscador de juegos .

Aqui teneis los links de la promocion:

Algun admin podria poner esto con stick para que no se baje , asi los nuevos que se vayan apuntando a Steam endran la info bien a la vista .
