A game without a game, an experiment in storytelling.
It's intriguing, and shows what you can do with a video game. Shows that you can be cerebral and unhappy.
There are no enemies to kill. There are no puzzles to solve. There is no action.
There is just a story, told in scraps of letters and clues scribbled on walls, and it's not a happy one.
It's ten bucks for the remade, fixed up, indie retail version of the original HL2 mod.
I highly recommend it.
Lets add a worn patina to all the items to provide a kind of extra contrast and call it HIGH DEFINITION!
