This early Half-Life 2 trailer, released around May 16, 2003, is comprised entirely of year old footage from Valve's cancelled presentation for E3 2002. The music was composed by Chris Jensen, the composer of the Half-Life: Opposing Force soundtrack. The track is actually recycled from many tracks cut from the Opposing Force soundtrack and is titled "Mishaps In The Reactor Chamber Part 1 - Track 03". Chris made the tracks available on SoundCloud after he exchanged several e-mails with Klow from the wiki but has since removed them.
