As reported on PC Gamer
Valve has announced that the Portal 2 Perpetual Testing Initiative puzzle maker has seen more than 35,000 levels published to the Steam Workshop since its release on Tuesday – and they’ve been downloaded over 1.3 million times.
In order to celebrate these really very large numbers, Valve have decided to make some other numbers much smaller: namely, the prices of Portal 2, Skyrim and TF2 Workshop Items on Steam. The ‘Weekend Workshop Sale’ will run until Monday and you can pick up Portal 2 for £5.09 and Skyrim for £23.44.
You can check out our first hands-on with the puzzle maker here, and if you’re picking up Skyrim this weekend be sure to browse the PC Gamer mod collections for the best additions to the game.
