Konami announced that there would be a “Metal Gear Solid V: Phantom Pain” companion app, which would be launching around the same time as the video game. The app will reportedly be similar to the one Konami released for “Metal Gear Solid V: Ground Zeroes,” which was essentially a demo for “The Phantom Pain,” but with a few extra secrets and side missions to do.

The app will allow players with a mobile device to access the iDroid that Big Boss owns in the game, according to IGN. The name iDroid is obviously derived from iOS and Android devices, both of which are compatible with the companion app that will be launched with the new game.

Fans who download the app will be able to listen to the music and records that Big Boss finds, as the game progresses. Downloading the companion app will also give players access to a better map than the one in the video game, as the tablet has a much better view of the area than the actual title for some reason.

Oddly enough, Pocket Gamer reported that the app would only work for the PS4, PS3 and Xbox One versions of “Metal Gear Solid V.” It seems like those that plan to purchase the game on the Xbox 360 or PC should not bother downloading it. Konami could always fix the problem with an update to make the app compatible with the Xbox 360 and PC, though no announcement regarding that has been made yet.

“Metal Gear Solid V: The Phantom Pain” has been a critical darling with reviewers so far, managing to get perfect scores. The game will be released to the public next week, so naturally Konami and Hideo Kojima recently released the game’s final trailer, which takes a nostalgic look back at the games that were released before it. This is Kojima’s last game, so the nostalgia seemed to be intentional.

The companion app will be available for download on Sept. 1 for both iOS and Android devices. “The Phantom Pain” will also be available on the same date and will be coming out for the PS4, Xbox One, PS3, Xbox 360 and the Windows PC.
