Interception is a single-player map featuring a fairly challenging puzzle involving two clean-style chambers, funnel, laser, and light bridge. The puzzle is somewhat more difficult than the official Portal 2 puzzles.
There should be 2-3 "AHA!" moments in the puzzle. The solution is not technically difficult to execute. If you find yourself frustrated or performing some stunt repeatedly, you should find an easier way.
Major Updates: Version 1.2 fixed a potential scenario where the player can become trapped in a chamber. Version 1.5 added one more "AHA!" moment. Version 1.52 compiled with high dynamic range rendering effects. Version 1.56 added elevator videos and GLaDOS speech. Version 1.58 added a Rattman den.
