Mount half life 2 episodes

[PresentDr.]

This has been suggested too much, but I'm going to suggest it again. These add new props and two new enemies along with a vehicle that appears in simphys but cant be used.

its been suggested once as far as im aware. you are also missing some extra things it adds. 3 enemies, more doors in the hl2 tools, a vehicle in vehicles section and one for simphys along with the extra props
