Half-Life 2 was released by Valve in 2004, with the mysterious G-Man addressing Gordon Freeman during its opening. The sequence uses surreal imagery, abrupt transitions, and the memorable “rise and shine” introduction to establish the game's uneasy atmosphere. Short effects associated with these visual flashes later became useful material for gaming edits, machinima, and meme videos. The white flash noise remains recognizable because it compresses the series' disorienting presentation into a quick transition that can make an ordinary cut feel ominous or unreal.
