Sorry but, wtf is this.
Self Explanitory.
All ammunition used in the video is 12x76mm Hydra-shok slugs.
Hydra-shok around the Clock = play on words of Rock around the Clock.
Same can be said for Rockin' around the Christmas Tree.
Jesus, you guys have no imagination
also it's at 2x speed because i'm a turtley player on STALKER (mostly because of droppin my gun when shot, vision punching when shot, etc), so it's got 2 times the gameplay.
