As PAX opened its doors, both myself and my camera man Daneil Carneiro made a bee-line for Valve, to settle down to see the new trailer for co-op mode in Portal 2.
We were utterly excited to see it, but after my fan-girl episode with Doug Lombardi at gamescom, I think I scared him. We were shipped off to interview the lovely Eric Wolpaw, writer for Portal 2, who gives us insight into the building of the relationships in Portal 2, and the many new features we can expect to see in the sequel.
