Not meant to be 100% accurate to the events following Half-Life 1 and the resonance cascade in Black Mesa. I also prefer quality over quantity in the mods, so I have made sure as to not have 100+ mods that people wouldnt want to subscribe to. Most importantly, I haven't seen that many Half-Life universe-related scenarios on the workshop, so I decided this would help those people who want it.

tags or some BS for people who're searching:
