We've waited many years for Half-Life 3, until this day comes... enter
Dark Interval!
Gordon Freeman is back in City 17 to learn of the aftermath since the destruction of the citadel.
Dark Interval is a very well made continuation of the Half-Life story with new characters, new features, new weapons and incorporating Half-Life assets with familiar characters like Barney, professor Kleiner and Dog.
Everything ran really well in Linux with Proton!
I previously never heard of this modification and after playing through Part II, I am thoroughly impressed!
Seriously! It's a great story with a lot of Half-Life-ish environments, puzzles and action! They did a very professional job creating a convincing City 17 and story!
I won't mention any of the new features, but I was excited to see new content which add to the story and development of Gordon Freeman as a silent character...
