Zeboyd's Penny Arcade: On the Rain-Slick Precipice of Darkness 4 isn't due out until later this spring, but in anticipation of PAX East, the developer has released a new trailer hyping the final game in the series.

Due to arrive on the Xbox Live Indie Game Channel soon, Penny Arcade: OTRSPOD 4 will bring the story of Tycho and Gabriel to a close, but not before introducing the largest game world in the series, all of which is fully explorable. While the full game isn't available yet, PAX goers will have a chance to play the game early this upcoming weekend during the Boston convention.

"On the Rain-Slick Precipice of Darkness 4 is shaping up to be our biggest, most epic RPG ever!" said Robert Boyd, co-founder of Zeboyd. "We look forward to everyone's reaction when they get a chance to play it."

You can check out a new trailer below, and let us know if you're excited for this final chapter in the Penny Arcade saga.
