-spain- -disc 1- -rev 1-.chd — Metal Gear Solid

The filename hints at a specific, perhaps older, iteration of the game, tailored for Spanish-speaking gamers, on a physical medium so archaic it's almost quaint: a disc. The "-Disc 1-" clearly demarcates this as part of a collection, suggesting there are more discs to come, each holding pieces of a larger, more complex narrative.
