|The Orange Box OST #||Game #||OST (Steam DLC) #||Track title||Filename||Time||Level location||Comments|
|*||01||04||Extinction Event Horizon||
||2:04||To the White Forest: The very beginning of the chapter, as Gordon is climbing out of the train wreck.||The title is likely indicative of the impending return of multitudinous Combine forces through the Citadel's superportal, which would result in a genocide of humanity, or an extinction event, and how this, for humanity's survival, would be an inescapable "point of no return," which in layman's terms is what an event horizon is in regards to spacetime in astrophysics.|
||3:14|| This Vortal Coil: During the final wave of the Antlion attack, in which the vortigaunts assist Gordon Freeman in the fight.
The song can also be heard during part of the Portal teaser trailer.
|The title is a pun on both Vortigaunts and the Mortal Kombat game series.|
||1:47||This Vortal Coil: When the Lone Vort finds the larval extract.|
||1:50||This Vortal Coil: During the G-Man sequence, when the G-Man talks to Gordon as the Vortigaunts attempt to heal Alyx.|

||0:12||Riding Shotgun: Upon finding the dead rebel before encountering the Barn Advisor.||This track also appears in Half-Life 2.|
||2:38||Riding Shotgun: During the scene with the Barn Advisor.||This track title is a reference to the Vortigaunt name given to the Combine Advisors.|
