With the 2.0 update, there are many new items that you will need in order to escape from the predicament you find yourself in.
One of those items you can see here, and since it is labeled I am giving you more information than I would normally do here (but I am feeling generous). You will need to use this item in order to complete the game, but as to where you can find it, and where you can use it - well, finding it is half the fun, and using it is the other half, isn't it. Suffice to say it will have to interact with at least one other thing in the White House. In doing so, it will be a great opportunity to check out our new "Use" screens, which shows pictures of both the item you are using and the item you are using it with. But if nothing else, you can at least make a note of what you can't do with it by using the new notes function in the game.
Can it get any handier? (If so, and you know how, don't hesitate to let us know via feedback@iAdventureGame.com and we will consider it for a future release.)
