After yesterday’s Portal 2 video introducing the new personality sphere Wheatley (see here), Valve has released two more videos from their E3 presentation. These two introduce players to ‘Excursion Funnels’ and ‘Faith Plates’, only two of the new elements in Portal 2 used to make puzzles more difficult.
There’s more to come. According to Valve, parts four through seven will be released throughout the week.
