Over 35,000 user-created Portal 2 maps created, 1.3 million downloads

Valve will certainly be GLaDOS.

Valve has fired an investigative drone into the bowels of the Steam Workshop, and it has limped back with the news that over 35,000 Portal 2 maps have been made and published since the launch of its Perpetual Testing Initiative on Tuesday.

That's a whizzy map editor, basically. The service has also seen 1.3 million downloads of these shiny new user-created tests.

Valve's launching a Weekend Workshop Madness party (okay, sale) to celebrate the company's riotous success: Portal 2's been dropped to £5.09 (even though it was still that price from the other day, but never mind), Skyrim's been slashed to £23.44 and Team Fortress 2 workshop items have been trimmed in pri-- OH MY GOD CHEAP HATS.

As usual, the weekend deals will run until Monday in the UK.
