"Fallout 4" is coming in a few days, but Bethesda is giving its fans an early treat by launching the Pip-Boy App.

The "Fallout 4" Pip-Boy app doesn't do really much as of the moment since you cannot connect it to the game. However, tech savvies found a way how to make it fun and interesting during the interim period, Kotaku learned.

The app is packed with a demo mode, and it can reportedly give you access to a few things, which includes fake character's stats, inventory, map data quests and more. It also has games, but at this point, "Atomic Command" is the only one available.

What you will do with this "Fallout 4" Pip-Boy app mini game is you stop the atomic bombs from destroying the landmarks in the United States, like the statue of the Liberty, San Francisco Bridge, the United States Capitol, Washington Monument, Space Needle in Seattle, etc.

A few tricks and tweaks, however, can add a few more mini games to the "Atomic Command." For example, the "Red Menace," whose gameplay is similar to "Donkey Kong."

Vault Boy will have to save Vault Girl, and instead of barrels, the communist is throwing atomic bombs. In the next level, the video showcases the Vault Boy walking against the conveyer belt and gains a Power Armor.

Other than the "Atomic Command" and "Red Menace," the tweak also adds "Zeta Invaders," "Grognak" and "Pipfall." Check out this video below.

The "Fallout 4" Pip-Boy app will let the user choose to go either on a full screen or hardware mode, which allows the player to adjust the display area so it can fit the limited edition harness, as soon as the app is opened, according to Android Police.

The app, which turns your smartphone or tablet into a Pip-Boy, has a UI patterned after the style of "Fallout" — green script on a black background.

The "Fallout 4" Pip-Boy app can now be downloaded for free from Google Play for Android and iTunes for Apple. This app is designed to connect with the actual game, which can be played on PS4, PC and Xbox One.

Pip-Boy does not yet include Apple Watch or Android Wear support, as per the report of Polygon.

Don't forget to mark your calendars for the arrival of the much-awaited RPG of Bethesda Game Studios. "Fallout 4" will be released on Nov. 10.
