Over the past few days Valve has been slowly releasing new footage for Portal 2 which was shown off at E3 a few weeks ago. Mike (x3sphere) already got a glimpse at the game behind closed doors however the rest of us were not so lucky. You’ll see plenty of footage that reveals new gameplay elements, including jump pads, excursion funnels, propulsion gel, and much, much more.

It looks like Valve is stepping up the complexity of the puzzles with these new game elements and are certain to bring about new challenges to the player. You can check out the footage after the break (one playlist, 7 videos).
