PSA: The Stanley Parable is out now, 20 percent off

The Stanley Parable is now available on Steam, and is 20 percent off ($11.99) until October 23. Originally a Half-Life 2 mod, the first-person exploration game centers on Stanley, employee number 427 of a nameless company, who pushes buttons on a keyboard at his desk as instructions appear on a monitor. Compared to the 2011 mod, The Stanley Parable "returns with new content, new ideas, a fresh coat of visual paint," and voice-overs by Kevan Brighting.

The game's description underscores the "everything is not as it seems" nature of the game, as over time "meaning begins to arise, the paradoxes might start to make sense." Developer Galactic Cafe encourages players to check out the game's demo to learn more, which is also available through Steam.
