Half-Life Overhaul Pack - it's a high-quality replacement pack for the original Half-Life models and sounds. As fan of singleplayer episodes I played a lot of the Half-Life mods, and all about improving of the playing experience were always interesting for me. So I made this package that can be used not only to play Half-Life as it is, but for playing different Half-Life mods too. Models and sounds included in this pack are not only my personal work. I'm just tried to gather some amazing elements made by other people, edit these elements and create new stylish replacement pack. I also had the task to save full functionality and classic style of original Valve's models for all of their replacements and don't forget to improve and fix all I can.
Here is another sample of using full-color Hi-Res textures under Xash3D engine for monster's model from Half-Life Overhaul Pack. I'm currently working on a full set of new HD-textures for alien monsters and I will try to improve all of them to the similar level of quality.
This is 720p HD-video, so better to enable full-screen HD mode in video-player when you looking it.

Why he makes sasquatch sounds?
These sounds are just a part of Overhaul Pack.
