Great vid but one point there at the end. The last part  where it says that to use   melee  weapon to stun mob that have  high health regen.  The heavy boltor  has a ability that does this  well it  is the #2 ability   and  will knock down most enemies an stop the regen process  making them  die in like 3  hit  where as i  could put a  full clip into it normally without budging the HP bar.

Just quickly went back and checked this video with one of your alpha rants and, the customisation video. The sound in those 2 seem to have less reverberation and, more clear. 

Nice gentle introduction, not bad though may I say the sound quality is not up to your usual standard. Well done.
