Portal 2's Co-op "Twice As Long" As Portal 1 News

Valve has revealed to TVG that its co-op campaign for Portal 2 is roughly "twice as long" as the single-player campaign from the original Portal back in 2007.

We recently had the opportunity to sit down with Valve's Chet Faliszek to discuss all things Portal 2, where we asked how long a play-through of the co-op is likely to take:

"It's weird because, Portal - by its nature - length is determined by your ability to solve puzzles. So, less smart people get a really long experience [laughs]... so a lot of value playing hungover," Faliszek joked.

"No, so the co-op's about twice as long as the original one: so however long that took you, co-op's going to take you twice as long. Single-player is... twice as long plus... a bunch more. It ended up we expanded out even more than we thought we were originally going to," he said.

Given that the original Portal took around 3-4 hours to play through, that puts Portal 2's co-op campaign at around 6-8 hours and its single-player at 8+ hours. Certainly sounds like a jam-packed game to us. Click through here to read our hands-on impressions of the new co-op mode.
