Portal follow-up coming to XBLA

The voice of GLaDOS made a cameo appearance at Microsoft’s E3 conference today to reveal the existence of : Still Alive which is coming to Xbox Live Arcade at some point this year.

Portal: Still Alive will provide more singleplayer gameplay, plus new challenges and achievements. No word yet on whether this is the same Portal 2 that had some spoilers leaked a few weeks ago.

Still Alive was named as a “2008 exclusive” on XBLA, which surely means that it will be coming to other platforms next year also.
