Valve claims that with the Portal 2 Level Creator, you are able to “easily create, share, and play Portal 2 puzzles”, enabling you to share your brilliant creations with the rest of the world by publishing your maps directly to Steam. Once you have done that, other players can browse, vote on and play Portal 2 your puzzle, and you can do likewise to others. Valve also mentioned that “selected puzzles will automatically be downloaded and installed inside Portal 2”, so this might just be your ticket to fame if you have a penchant for churning out some fantastic puzzles in the past. I am quite sure that Portal 2 fans already have this killer puzzle brewing in the head as they read this…
