Lockaon (CS:GO + Half-Life 2 mashup)

well I never thought I would make a mashup with a Counter-Strike song, but oh well, I'll still put it in the Portal/Half-Life music playlist anyway: https://youtube.com/playlist?list=PLO3z4klBKvjbWVyu2yh2AxB1Qo-JhXrjb I don't play Counter-Strike or Left 4 Dead, just Portal and Half-Life games
