Half-Life Walkthrough ("Hard" Difficulty, 100%) - Chapter 1: Black Mesa Inbound.

Hello and Welcome Everybody to my next 100% Let's Play or Walkthrough. This is for the 1998 released legendary First Person Shooter, Half-Life. I was really looking forward to this in particular and yes here it is.
Now one quick note before anything, is that I'm playing the original 1998 release with the Half-Life Launcher (Basically a Source Port to run the original Half-Life) and not the HD Texture Pack. Now, yes I'm playing this on 1920 x 1080 Pixels to make it look more detailed, but trust me I'm not using the HD Texture Pack, because it sucks. Anyways!!!
This is Played on the "Hard" Difficulty setting going for the 100%.
