General Features: The iDroid is, especially for 1984, a versatile device that allows you to manage Mother Base, view maps, look at statistics and so on. Here we'll only go over the most obvious things that could be useful for navigation. One important thing to take note of right away is that time does not stop in-game when you pull out the iDroid; the game is not paused and mission time will continue to flow away, or worse, enemies can spot you and trigger alert or combat statuses. Keep this in mind.
Th[Subsistence] iDroid Map: You can place markers at any place of the map. These will appear in-game with a distance counter, which can be very useful to navigate both larger and smaller areas. When you arrive at the marker, it's automatically removed. The map also shows you geographical details such as elevation, allowin you to plan routes through rocky areas without having to go back due to bumping into dead ends.
- The map icons are quite straightforward, but an additional description could be useful. The player is depicted by a white triangle, followed by white dots indicating where you've just walked. Green and red upside down triangles depict friends and enemies respectively. Blue and yellow circles mark regular or important side ops missions, while a small orange circle depicts your last known position to enemies. A chopper icon speaks for itself, being a heli landing zone. A small flame depicts resources, usually added to your map thanks to interrogation intel. Marked objects are white squares, and mission objectives are yellow squares.
Extraction by Chopper: You can use the iDroid to call in a chopper to pick you up. Select a landing zone close by and make your way over. Since it takes at least a minute for the chopper to arrive, anticipate the future and call in extractions on time. The same goes for supplies (see below).
Ordering Supplie[Subsistence]: You can order supplies from Mother Base at any time while in the field, and you should definitely use the option whenever you feel it's required; that's what the whole infastructure is essentially for! It does cost some GMP and impacts your mission score, but the benefits are so high that it's silly to sit around with empty guns, which will impact your mission score all the same. The package will arrive in about one minute after you order it.
