Attack with Weapon
Use the triggers on your controller to aim (left trigger) and shoot (right trigger) with the weapon you’re currently holding.
Select a weapon to equip using the D-pad. For those with multiple choices (such as support weapons), use the right stick while holding the D-pad to select the one you want to use.
Some weapons, such as tranquilizer guns, can neutralize enemies without harming them.
Such weapons will have a blue icon on the selection screen.
Enemies that you neutralize by knocking out or putting to sleep will sometimes recover.
Headshots immediately neutralize enemies. With lethal weapons, enemies die instantly. With a tranquilizer gun, they immediately fall asleep.
Close Quarters Combat (CQC)
Attack nearby enemies with hand-to-hand combat. A variety of actions are possible with different button combinations.
This enables you to neutralize enemies without the noise of gunshots.
To hold up enemies, approach them from behind or without them noticing and aim your weapon at them.
You can extract various kinds of information from the enemy by interrogating them.
Spit it out
Obtain information that will help you in your mission.
Where are the rest?
Learn the positions of nearby enemies.
Make your opponent lay flat on the ground (only while in the Hold Up state).
If you touch a dropped weapon, any remaining ammo will be added to that of weapons in your possession that use the same ammo.
You can carry two primary weapons (one at your hip and another on your back), two secondary weapons, and eight support weapons.
Additional weapons that you obtain will have to be swapped out with those you are carrying.
Weather and Time of Day
Time in the game passes at a fixed rate.
At night, your visibility is reduced and enemy guard shifts change. The weather also changes along with the time of day.
Sounds are less audible when it is raining, and visibility is limited during a sandstorm.
Extracting soldiers from the area of operations is essential to expanding Diamond Dogs.
Approach an unresisting individual (either unconscious, asleep, or held up) to Fulton extract them.
After developing better Fulton extraction devices, you will be able to extract objects as well, including vehicles, materials containers, and weapon emplacements such as machine guns and mortars.
The success rate of Fulton extractions depends on factors such as your Support Unit's level, the weather, and the subject's physical condition.
You cannot perform a Fulton extraction when there is a ceiling above you.
