The Penny Arcade team have launched the beta version of its new digital distribution service called Greenhouse, which will work much like Gamers Gate or Steam as players will be able to purchase independent titles and then download them straight to the PC.
The only title that has currently been announced for Greenhouse is Penny Arcade Adventures - On the Rain-Slick Precipice of Darkness: Episode One which will be sold for $19.95, although no release date has been provided on the website but it should be released fairly soon.
But if you want to get into the action already, then you can download a beta build for testing. Or you can take a survey, that's if you've got the time for it.
You should head to the official Greenhouse website to find out more about this new service.
