Its more like
1: Strider A and Gordon/civilians fight, gordon runs behind combine APC, strider kicks APC at him, he goes behind the pillars, strider B destroys pillars with laser, strider A fires at gordon with laser and takes half his health, strider B fires laser again at gordon and he dies...
I just watched it again and actually a different Strider destroys the columns each time. The physics control how they fall and that isn't really scripted as much as it is identical calculations, so whatever.
Look very closely. They reskinned the police from 2003.

I'm starting to just ignore anything posted about HL Radio having anything. Every time I tune in they never do.
Even after posting a news post saying they do. o_O
