The final chapter in Penny-Arcade's foray into videogames is now available for purchase on Steam for $4.49
Penny-Arcade: OTRSPOD Episode 4 brings the tale of Gabe and Tycho's videogame adventure to a close, and is now available on Steam for $4.49, with an Xbox Arcade release "coming soon." From the website: "The new game expands considerably on its predecessor in size, scope and gameplay. Create the ultimate fighting force by recruiting bizarre, occasionally disgusting monsters and teaming them up with the best trainer for the job."
Penny-Arcade Adventures: On The Rain-Slick Precipice of Darkness has a long name and an ever longer development cycle. Episode 1 originally debuted all the way back in 2008, and was developed by Hothead games. It was an adventure-rpg with 3D models, staring Gabe and Tycho as stylized versions of themselves (despite the fact that Gabe and Tycho are already stylized versions of the Penny-Arcade authors) living in "ye-olde-times" (perhaps the 1920's?). Episode 1 and the subsequent second episode were overwhelmingly average, especially considering the duo's internet fame.
Apparently, Hothead felt the same way, opting to discontinue its development of further episodes in 2010. It looked like the Penny-Arcade project was dead, until Zeboyd Games stepped in in 2011 and announced it would develop the final two episodes, albeit in an entirely new graphical style.
The third episode was released in 2012 and sported some totally retro pixel-art visuals, and felt much more like a Penny-Arcade game. It was also made available on Android and iOS devices, whilst the first two episodes were exclusive to PC and Xbox. We can probably assume that this forth episode will also makes its way to the mobile operating systems at some point in the future.
