Half Life 2 Walkthrough With All Achievements On Hard Part 7

In this video i finish up chapter 4! I get the final lambda location of the chapter for the "Lambda Locator" achievement. I also get 3 other achievements. Those achievements are: "Heavy Weapons", "Revenge" and "Vorticough". I also died a couple times in this part. One death to an exploding barrel and another running through the toxic sewer for the last achievement in the chapter. Thanks for watching!
