Have you tried so hard to create a Portal 2 level in Valve’s “Source” engine but find it really difficult? Not to fear, as there’s new DLC to help with that on the way.
Valve have announced free DLC for the PC/Mac titled “Perpetual Testing Initiative” which “allows players to easily create, share, and play Portal 2 puzzles. The Initiative comes with a simplified puzzle maker that allows that creation of mind-bending puzzles without ever leaving the game.”
Once you’ve made your level, you can upload it to the Steam Workshop, where people can vote, share and play your levels. If you’re lucky, your levels may even be installed into the game itself.
The free DLC will become available on May 8th. There’s no word on an Xbox 360/PS3 release, but to be honest, I don’t see that actually happening. Ever.
