‘iDroid’ is the name of Snake’s handset in Metal Gear Solid V: Ground Zeroes!
Opening it up during the game, however, can leave you vulnerable to an attack by the enemy but don’t worry because you can download the iDroid Metal Gear Solid V: Ground Zeroes Companion App for your real life smart phone!
This allows you to use it on your Xbox SmartGlass™ system or any device with iOS 6.0 and later or Android 4.0 and later and access the same menu on a second screen!
Some Xbox 360® features require the use of Microsoft®'s "Xbox SmartGlass™" application. Refer to the Xbox 360® homepage for details.
If you interrogate a guard, he may give you a hint as to a location of a weapon. This will pop up on your map as well as any vehicles you mark yourself. You can call support helicopters and even play back the Cassette Tapes you collect whilst on the move.
The free iDroid Metal Gear Solid V: Ground Zeroes Companion App is available since 20th March in Europe and 21st March in the UK, the same release day as Metal Gear Solid V: Ground Zeroes!
Certain features within this application require a local WiFi connection.
