The Division is a cover based, third person shooter with character based RPG elements.
The basic controls allow you to walk or sprint around the environment and also to climb over and onto obstacles / objects. Holding the climb button as you sprint towards a fence / wall / vehicle will let you immediately vault over or on to it. Clearing fences in this way lets you continue to run without stopping your progress forwards.
You are heavily encouraged to use cover in the environment during combat and this works pretty well and is generally essential to make surviving most Encounters far easier. The only downside is that being stationary behind cover can lead you to miss the odd enemy that chooses to run up to you from the side to attack you at close range, often with a baseball bat. So try to keep a note of all the enemies in an encounter.
You are equipped with a primary main weapon and a side arm, and later you gain a secondary main weapon. Pressing or double tapping 'Y' on xbox switches between the Weapons.
The Weapons and other equipment in the game can be bought at Vendors but also collected from some fallen enemies or crates in the game. Although these pickups are not common.
Keep an eye out though for some containers and packs in the game world as they can give you medkits and other items. As well as the restock crates that appear in and around mission areas to refill your ammo.
Yes! There are red barrels in the game. Shoot when enemies are near and benefit.
