I installed this app for Valve's PC "Portal 2" and was very disappointed when I discovered it was for the Xbox. I'm only suggesting you make it clear that this is for Xbox, or make a PC version of this app.

This was a great app is very helpful in what achievements I need to complete the game, but an in-app video player for video tutorials and landscape orientation would vastly improve the app.

An amazing app for achievement hunters such as myself. This layout is the best for what you used it for.

I am looking for a guide for portal 2 to help get through levels. But sure it is good for keeping track of achievments.
