The Audio of Infinite

First off let me say 99% of the audio is amazing. The guns the classic recharge of the shields. The needler.

My only note would be the Frag genades but since that could simplbe me. What do you guys think?

What part of Infinites audio has you happy and exited and what do you think could use a polish ?

A lot of the guns sound so amazing, have no problems with grenades tho
