Portal 2 gets over 38,000 new levels

Science! Portal 2‘s freely available level editor DLC — Perpetual Testing Initiative — has caused a rush of new content to the first-person puzzler.

Over 38,000 user-created levels have been created since the few days the editor has been available, with more popping up constantly. They’ve been downloaded over 1.3 million times.

You can go through the selection on Steam Workshop.

If you’ve yet to play the game, Valve is making it extra, extra sweet for you; the game is 66% off this weekend.

If you’ve yet to play Skyrim, that’s received a discount as well: 33%.
