This game is not related to the story of the Half-life2.
Something goes mad because the human race failed in the
experiment, and it connects with another world.
The resident in the another world is crazy due to the mistake.
We should restore the situation.

As for this game, almost all are made only from the basic function of HL2.
Having fiddled with the code for the chapter unlock is the only exception.
You will learn the degree of freedom of the expression of HL2 is very high.

Quite playful and imaginative mod, certainly one to divide opinions. Puzzle-wise this mod totally got me, I couldn't figure out all the puzzles/bosses easily, because the game doesn't exactly state when you should stop and think and when to look for a hidden passage or when to find a "soft" spot on the floating metal enemies. But on the positive side the puzzles, architecture and level design was rich in imagination and broke certain boundaries when it comes to what we're used to seeing in HL2.

I have no problem admitting the mod left me feeling stupid since I couldn't figure out what to do in the final room. I'm not going to spoil it to you but just know that there are hints for many puzzles on the web page so I suppose I'm not the only one to have trouble following the developer's train of thought.

If someone described the mod to me I'd be sure I'd just love it but still after playing through I feel like it left me annoyed. It's like that shiny white minimalistic overpriced Apple product amongst all the "normal" gray/black wares for the ones that wish to stand out. Or an abstract painting no one can quite figure a thing about but say that they like it just to be safe side.

No one's going to judge you if you say you liked the mod but it takes guts to say it wasn't for me. What's exactly wrong with it is hard to explain but in 2 words I'd try to summarize it as "learning curve". But don't take my word for it, play it for yourself.

One of the first mods I ever played. Loved it back then, and redownloading it now for nastolgia.

A mod you love to hate and hate to love... Brutally challenging both your mind and your reflexes but also often incredibly breathtaking and surprising in aesthetic and imaginative terms... Simply another level of game art... 10/10

This mod is hands down one of the most brilliant, intuitive, and creative mods out there. It expresses it's own artistic nature very thoroughly without fancy high quality brush work.. and that particular shortcoming never surpasses through the true epicenter of were this mods greatness lies. This is a shining example were it truly shows that gameplay, atmosphere, and story are FAR more important than visuals, fancy looks, and high resolution textures. This is one of my favorites of all time - hands down. :D

Sweet Half-Life and Peaces Like Us are both mods I also absolutely adore. I'm a huge fan of K.S. :)

A review to be buried:

This is indeed a mod worth playing. Hell, this is one of the first mods I downloaded, which were selected with much care and many positive reviews. There were parts that bugged out like crazy for me *spoiler* like the time when Alyx and friends didn't accompany me when I fought the flying tube. But the art design and mapping is indeed superior to many mods, and these days you just don't find many Half-life 2 mods where the Combine AND the Rebels are your allies. The custom bosses are an immense treat and the music is just plain addicting to listen to. This mod sports a rock solid number 9 out of ten.

The only way i can express my appreciation for this experience is by mailing my organs to you. A pleasure to play, very good distictive style and there were very fun and unique gameplay elements.

Everybody with HL2 should play this.
