This looks like a test for a trailer that never was. The pop in is clear but I strongly suspect is simply a scripted event that was never fixed as they didn't go ahead with this trailer - i.e. all of this is scripted in-game engine to make a trailer and wasn't polished so the early errors in timing, etc. are still there.
The huge mech walker plus the new throat tearing Chimera do bode well though.
Try to be reasonable... its easier than you think...
