Thanks to developer Zen Studios providing me with early access, I've spent the weekend exploring the company's newest pinball table based on Valve's popular Portal series.  Watch as I set a new high score by completing missions while GLaDOS takes shots at me, Wheatley interferes, and Ratman lurks in the shadows.  It's another winning table for Zen Pinball 2 and Pinball FX2 with plenty of fun little touches from the series.  The Portal table is available across the Zen product line starting this week.
