where are the sparks?

I was watching the Halo CEA gun sounds video, and I realized there might be more tinier sparks but there’s no big sparks at the force of impact or even any marks on the wall showing there was bullet damage or plasma damage.

Will this be polished before release or are we just going to have to suck it up? (or maybe im just too used to BF3)

Those were some big bullet hole in the BF3 beta. Also the BTS video for campaign and the walkthroughs never really showed them shooting a wall. the sound and effect video 1 show that rock chunks do fly when you shoot the rocks still.
