About This Game

After a tragic accident, neurobiologist Dr. David Styles has become a recluse, rarely leaving his home, the Dread Hill House. One day, Samantha Everett, a street magician, appears at Dr. Style's doorstep just as he is seeking a new assistant.

Samantha's first task is to find six people to form “The Lamb's Club” of human guinea pigs for Dr. Style's tests at Oxford University. The experiment starts off innocently enough, but then a chain of inexplicable incidents begin to occur, one after another.

Are these experiments as innocent as they appear? What is the true aim of Dr. Styles' research? What secrets are waiting to cross over from the other side?

In Gray Matter, legendary game author Jane Jensen (creator of the Gabriel Knight series) tackles questions concerning the nature of reality and the power of the human mind in a mystery adventure that comprises 8 massive chapters. Jensen combines the elements of science and the supernatural, together with her acclaimed emphasis on character and story to create an unprecedented paranormal experience that will keep you riveted until the very end.

+ modern point and click adventure game, with nice presentation and incredible soundrack
+ fantastic writing, great dialogues and good voice acting, very deep , dark at times mystery story about neurobiology and the possibilities of the brain as well as magic
+ likable protagonist, great npcs, dr.styler a very well thought character with dark secrets
+ classic point and click gameplay, with the interesting addition of magic, where you have to play a sort of mini game when using magic according to each cirmstance, you have to read the manual (ingame manual) and experiment a lot in this department, it can become frustrating at times, but also very satisfying when you figure out how to use it
+ excellent score system where you track your progress in each chapter

- a bit stiff animations

+/- pressing space reveals all hotspots in a scene, they could skip that since it ruins the exploration, some casual players might find it very usefull though, since the game can become difficult at times

have played it retail and finished it once, now i repeat it on steam, it's imo one of the greatest modern adventure games and i recommend it to all adventure gamers on steam.

A funny little gem of the post-Golden-Age of adventure games, Gray Matter possesses a certain charm that contains a humble nostalgia. Like its author's previous game, Gabriel Knight: Sins of the Fathers, the story of Gray Matter revolves around the supernatural. A young American street magician traveling Europe chances upon Oxford hermit Dr. David Styles, whose mysterious nature and odd experiments cultivate an air of mystery.


-- Solid atmosphere, great writing, and an intruiging story all make Gray Matter a cerebral experience.

-- Though it boasts dated graphics, the engine holds up well enough. I rarely felt it inadequate, and sometimes it was quite attractive.

-- Most of the puzzles, while not difficult per se, are satisfying.


-- Some of the voiceacting is either uninspired or poorly timed.

-- A few of the puzzles are TOO easy and simply feel like busywork (example: Samantha needs to steal a key, so she uses a magic trick that requires another item. Sam goes to another location, purchases the item, and performs the trick at the former location. But now she needs to purchase ANOTHER item to perform a second trick to distract someone, which involves backtracking again)

-- The music can get pretty repetitive.

Overall, Gray Matter offers a fun, engaging experience that will feel familiar to adventure game veterans. It's a great game for newcomers, too, since its puzzles aren't quite the non-sequiturs of yore; still, its approach to adventure is satisfying because Gray Matter's writing is so very apt.

I own all Gabriel Knight games as well as the books and I'm so glad this game is finally available on steam.
I have finished this game before but I didn't hesitate one second to buy it when I saw it on the frontpage of the steam store.

When I was younger I got a demo of one of the Gabriel Knight games from a PC magazine I had a subscription to and played it over and over and a few years later It hit me that I had to get the games I discovered when I was younger since they have always been in the back of my mind.

Gray Matter brings back all the feelings from the early point and click games, and it truly is one of the best of its genre.
If you are interested in puzzle solving adventures with great storylines this really is a game for you and for its price it would be foolish not to give it a go.

Recommended for anyone who likes adventure games for their story, settings, and characters. If you're a fan of magic (as in magic tricks), then this is also a special treat.

This title is made by Jane Jensen of Gabriel Knight fame from the "golden age" of adventure games. As far as writing a compelling adventure game, she knows what's doing.

Technically, there are some issues, and lack of polish in places reflects the limited development budget. But all this is forgivable, I think.

Mentioned in the description, but not shown in the screenshots (probably rightfully so, to avoid spoilers), the chapters actually alternate between two playable characters. This ability to play "two sides" of the story is a major feature of Gray Matter.

This isn't a puzzle oriented game. You won't be stuck hunting pixels. Progress is mostly straightforward. Each chapter has several main tasks you need to accomplish that are sometimes dependent, but sometimes allow you to explore in an order of your choosing. Note that sometimes the game expects you to arrive at a particular location to progress (this confused me twice).

Be warned that the game starts off somewhat slowly in the first few chapters, but gradually picks up pace. Stick with it until at least the third chapter before deciding to give it up.

Gray Matter is a point&click adventure game by Jane Jensen. Need I say more?
It's very well written, clever and ever so interesting. The protagonist(s) are rather unique and definitely not your usual, avarage Joe characters. They are likable but not without some obvious flaws (like Samantha likes to jump to conclusions really fast). The puzzles (especially the Daedelus riddles) are exciting even if the game is a bit easier than I'd like. Overall the game still looks nice even though it's years old (despite what the store page says) and the soundtrack is amazing (even if it's only a few songs).
I highly recommend playing this!

One of the best adventure games i have played, and I’ve played a lot of them.

The story is really great and keeps you playing. Characters are deep and well though-out.

The Music is phenomenal, very climatic and gives really a lot to the game. One of the best soundtracks I’ve listened to.

If you like old-school adventure games this is your jam (and who am I kidding. If you like the genre you probably played it a ton already)
