Just a quick heads up here on a major weekend sale that's underway on the highly popular�Penny Arcade Adventures: On the Rain-Slick Precipice of Darkness, Episodes One [$0.99] and Two [$1.99], both down from $7.99 for 87% and 75% price reductions, respectively. Both titles are also available on XBLA, PSN, and Windows, but these are the lowest prices we've seen for them on any platform.

As described by creators Penny Arcade and Hothead Games,

On the Rain-Slick Precipice of Darkness is an RPG-Adventure game set in the comic-book-meets-pulp-horror-meets-H.P. Lovecraft deranged 1920s universe of New Arcadia, delivering mature and compelling entertainment to gamers via accessible episodic delivery. The creative collaboration between Penny Arcade creators Mike 'Gabe' Krahulik and Jerry 'Tycho' Holkins, legendary game designer Ron Gilbert and veteran producers Hothead Games results in a 100% authentic Penny Arcade experience that pushes bizarre characters, outrageous combat, and adult humor to the precipices of darkness.

Players join Gabe and Tycho, the crime-solving team of the Startling Developments Detective Agency, to combat savage enemies and solve mysteries hidden deep in the sinister heart of New Arcadia. The ominous 1920s landscape features distinct artwork and characters designed exclusively by Krahulik and brought to life by the Hothead team.

Gamespot called the adventures well worth the initial XBLA price of $20 USD for any Penny Arcade-loving gamer. Any Mac user who meets that description should find this weekend sale an absolute steal.
