The UHS gives you just the hints you need to solve many games. We give you as much detail as any walkthrough, to help you finish. But unlike ordinary walkthroughs or cheats, we show you just the hints you need, so your game is never spoiled. Select the area where you're stuck and then keep clicking "Show Another Hint" to get the right level of help – anything from a small nudge to a full answer.

You can either view these hints for Portal 2 for free from our website, or for more convenient and ad-free access, use our UHS Reader for Windows software.
