Grey’s life has been nothing but a struggle. A constant downward spiral, and it seems even reality has turned against him. Grey awakens to find that the world has gone quiet, the streets empty. You must find help. Explore the grim world Grey lives in a completely new and unique world, and find clues to his shattered past. Grey is a total conversion Half-Life 2 horror modification where the player must solve puzzles, fight to survive, and find out what is happening to the world around you. We have made a lot changes to the base Source engine and have added countless new mechanics in the mod such as the objective indicator, portable medkit, donator based extras, pickup animations, failed reloads, new picture based GUI elements and much, much more!

Grey reminded me of Cry of Fear the first time I played it. The twisted madness and storyline was very well done for a free mod.

I love how they made the ventsystem. It feels like you are dwelling deeper into the darkness by going through it with all that weird net that looks like a nerve system.

It has a lot to offer content wise. After beating the game you can play it again in a higher difficulty and the good thing is they changed a lot of stuff which makes it very enjoyable to play it again.

I can easily see how much passion and time they put into this game.
They even added a challenge mode and a bonus map into this game which I highly recommend to try it out :)
