Portal 2: Co-op demo impressions from PAX 2010
More reasons to want Portal 2, if you didn’t already have enough

Best homework ever: Portal recognized as a legitimate academic text
The cake is not a lie. It’s an insight into the human condition. Seriously

    So... Blue only has blue portals, and Orange only has orange portals? Is it set up so that Blue's portals can only connect to Orange's? Or are the portal sets independent?

    I can tell Orange and Blue are going to form bonds with the player even more than the companion cube did. I kinda felt bad when Orange got crushed just from the trailer!

    Radical.? Bitchin? Boss? All of the above (yes)?

    Why did I immediately look at this and think about grieving...? I mean, I'm going to play properly. But if there so happens to be split screen.... YAH! Into death pit! YAH! Fired at full velocity into wall! YAH! Explosive platform triggered. Lots of fun >:3

    this story better have a twist. it's just not a good portal story without a twist (i know there was only one but come on)
  • EnragedTortoise1 - September 10, 2010 9:33 p.m.

    THis has now surpassed priority to the 3DS. WANT NAOW.

    Oh my God...I want to meet the writers for Valve someday. They are absolute geniuses. If they made George Bush's speeches he could come back for 2 more terms.

    This trailer implies this is ALL gameplay footage awesome cant tell it apart from video
  • Jacko415 - September 10, 2010 8:02 p.m.

    fuck yes!
  • IsaacFenix - September 10, 2010 7:59 p.m.

    "Don't disappoint me, or I'll make you wish you could die." How I've missed GLaDOS and her threats.
  • CrashmanX - September 10, 2010 7:52 p.m.

    Do ho ho. It looks to be quite a bit of fun. I do want badly.
  • 510BrotherPanda - September 10, 2010 7:30 p.m.

    Does Orange suppose to more feminine or something? It's an awful lot curvier than Blue.
  • dutchieslandgaming - September 10, 2010 7:29 p.m.

    This looks awesome!
  • Ded - September 10, 2010 7:25 p.m.

    Hurray for Orange and Blue!
  • pepheb - September 10, 2010 7:16 p.m.

    I dont know why, but when the orange robot got crushed and he came back, I was like "aaaaaaw" when the blue one gave him a hug XD
