There are more than a few great things in this video (which covers the first part of our E3 single-player demo; six more parts are expected this week). The first is the introduction of a cheeky, British personality orb. He's cheeky, British, and we already love him. And GLaDOS. Oh, GLaDOS, how we have missed you. Anyway, just try to watch this video without smiling (or outright laughing). We dare you. Go ahead. You monsters.
