Steam has been a very good boy today: first he starts accepting money for Valve's super-highly-anticipated Left 4 Dead, and now he brings you, as promised, PopCap's Peggle Nights--at a deep discount, even.

The pachinko-esque ball-bouncing sequel released last month to rave reviews from Shacknews editor Chris Faylor. He didn't so much play the game as giggle at Bjorn the unicorn and eat PopCap cookies, but it was a resoundingly positive review. Now that it's on Steam, Peggle Nights' price was slashed by half, retailing on Valve's digital distribution service for $9.99. It's available now.

Seeking to further its grasp on the hearts and minds of millions, casual game developer PopCap Games today released a sequel to its unicorn-centric and rainbow-tastic PC bouncing ball effort Peggle.

Dubbed Peggle Nights, the sequel features "a dreamtime adventure of alter egos and peg-tastic action," and once again requires players to eliminate colored pegs within a certain number of shots. According to PopCap, Nights is more focused on skill than the original, with more levels set to be released as downloadable content.

A free demo is currently available on the game's official site, with the full version priced at $19.95. "OMG OMG OMG OMG OMG OMG!!!!!!!!!!!!!!!!!!!!," exclaimed beloved Shacknews community member dognose.

Much like the original Peggle, Nights will soon appear on Valve's digital distribution platform Steam, with its Steam debut slated for the nebulous "next month." A list of the sequel's key improvements, as highlighted by PopCap, follow below... Read more
