It's time to get crackin on the custom content! The Portal 2 Authoring tools have been released
Portal2 was deliciously awesome but one of the things that made Portal so great was the custom content that followed, so the announcement that the Portal2 tools are ready to go, is very much welcome! I can't wait to see what the community cooks up.
"Today we're opening up the beta of the Portal 2 Authoring Tools to everyone! It's available as a free download for all owners of the PC version of Portal 2 and can be found under the "Tools" tab in Steam.
The Portal 2 Authoring Tools include versions of the same tools we used to make Portal 2. They'll allow you to create your own singleplayer and co-op maps, new character skins, 3D models, sound effects, and music."
