The Rumble Pack is down to just a Rumble Couple, but we’re not skipping a week! This week, Justin and Kaz dive into tons of random stuff. Justin flies through Portal 2‘s co-op test-chambers, crunches numbers in Etrian Odyssey III and protects the woodlands of Gatling Gears by laying waste to them. Meanwhile, Kaz brags about his Pac-Man C.E. DX Windows Phone 7 port and catches the Mortal Kombat bug. And while they’re still fresh out of the L.A. Noire academy, Justin and Kaz are eager to talk about what the game means for Rockstar…and whether or not it will be the most returned game of 2011. Plus, robodogs, ghostly powers, dated mechanics and dubious assessments of the game industry economy.
