This is absolutely stunning, i am beyond impressed by this.

Through the entire experience, i had almost no performance issues on my shitty PC, beautifully optimized.

The story, while not the most complex, is gripping and had me engaged, i love how alive the world feels, everything from a guy in a bathroom stall yelling at you when you try the door several times in a row, to the smallest little NPC interactions.

There were several moments in this mod that had me saying "wow.. fucking genius" aloud.

I've dicked around with HLA mod campaigns for fun since the game came out when i was like 14 or 15, other mod campaigns have been pretty satisfying but nothing has compared to this, it blows my mind that its FREE to play, these are truly passionate and insanely creative people that worked on this!

Absolutely perfect HLA mod, hope this sets a new bar for other devs, not to discredit anybody else but this is a masterpiece, great work :)

At first, I thought it was Johnwick of the club...
It was more difficult than I thought, and there are parts that need to be sensible
Modes of how much fans respect this game

I gotta admit the zombies on the dancefloor in the screenshots put me off - I've seen too many gmod maps take the same route -- but in the context of the whole campaign it fits: this feels like a fever dream, and an awesome one. That ending fight sequence was amazing.

Great map!

Just played it again and I really enjoyed it, more this time then in the beginning (for me). There are many curves and twists in the mod for anyone to have a good time, something for everyone...
