Expansion of Mother Base
Early in TPP, you will only have access to the ‘command platform’ of the Mother Base. As you progress through the game, you will be able to expand MB in different directions and acquire different specializations.

However, do note that expansions and specializations will require in-game money and time. Moreover, you can use the Fulton System to send vehicles, weapons, and soldiers to MB.

How to Recruit Soldiers
One of the easiest and certain methods of recruiting soldiers is to kidnap them using Fulton Recovery System ‘FRS’. Once kidnapped soldiers reach MB, they are automatically recruited for the Diamond Dogs.

You can use your gadgets to check soldiers’ stats and see if they are worth it to be a part of the Diamond Dogs or not; this and also because your get limited FRS balloons on a mission.

In addition to this, you can also send in your support team to search the world and look for potential volunteers who wish to be a part of your unit.

Departments in Mother Base

There are different departments inside Mother Base which are occupied by your staff members and companions. Here are different departments and their uses in Mother Base:

Medical Facility
This is where injured soldiers are treated and healing items are processed using collected medical items.

Information Retrieval
This is where building plans and blueprints are formulated. In addition to this, it also contains intel for the areas where the Diamond Dogs are currently active.

Base Development
If you wish to develop MB more efficiently, you need to add some resources in this department. It is in this department where collected resources are further developed.

Support Unit
This is the unit which provides you with FRS, airstrikes, help you translate different languages, provide distractions, and also provide fire support.

Combat Units
This carries all your best fighters and mercenaries. You can send out these mercenaries to find and recruit new soldiers, destroy enemy infrastructure, and many other things.

Research and Development
This is the department where you develop new pieces of equipment, gadgets, and even weaponry. The more staff members you invest in R&D department, the faster your pieces of equipment will get developed.

In addition to this, there are departments which help you improve the skills of your buddies such as Quiet.

Mother Base Customization

Although you have no control over how each extension of MB is built, you can change its colors and some minor changes. In addition to this, you can also change the Diamond Dogs standard emblem to your liking.

Forward Operating Bases ‘FOBs’

FOBs are basically the online extensions of Mother Base and can be built once enough resources have been gathered. You can create one or more FOBs which will greatly enhance resource gathering and other things.

However, unlike the Mother Base, you can infiltrate another player’s FOBs and get infiltrated in return.

While infiltrating, you will be able to steal and fulton supplies, weapons, and so much more. Your biggest target, however, is to reach the central core and exfiltrate without getting caught.

Once a player infiltrates an FOB, the owner is notified and can send in friends, let the AI-controlled security team handle the matter, or go in himself.

Do note that even if a defender is killed, he will respawn as another member of the security unit, but attacker only receives one life and dies permanently; losing everything stolen.

Aerial Command Center
In order to return to MB, you need to visit ACC and access your iDroid. From the ACC, you can choose any available mission or side-ops. Furthermore, if you wish to launch a mission on a different location, you need to access ACC. Lastly, weapon customization is also performed on the ACC and is acquired after completing side-op 109.

Showers and Secret Cinematics
Showers are also available in the Mother Base and can be accessed by Big Boss. Aside from washing away dirt, Big Boss also enjoys some temporary bonuses such as increased HP and reflex mode. Furthermore, you can also trigger optional cut-scenes while you are in MB.

Target Practice
MB also houses seven Target Practice side-ops; each on a deck. You can play them at any time without any fear of failure and as many times as you want. These are typical target practice mission which require you to shoot down dummy targets scattered across the area.

Animal Conservation Platform
In order to use ACP, you need to extract six wild animals and complete mission-7 to mission-10. ACP is not directly connected to MB and is accessed via ACC. Here you can observe different species of animals among other things.

Upgrading Base Facilities
You can upgrade different platforms by adding expansion called ‘decks’. Doing this not only expands your MB, but also increases the staff stationed at each platform. Each platform can be upgraded four times and requires different material and a specific GMP cost.
