Games in the shooter genre are typically pretty straight forward when it comes to certain parts of the gameplay. Grenades are typically as simple as they come with being tied to the bumper or trigger buttons, but in The Division they are a little more complicated and confusing.
There are many times in The Division where you are facing a horde of enemies that are hard to even shoot without getting hit hard due to the number of them. This is where grenades come in very handy, but you have to know just how to use them.
By holding down left on the d-pad, a selection wheel will pop up that lets you switch between grenade types. You can choose the one you want with the right analog stick and you would assume that would then let you use it right then and there. However, that is not quite how it works.
Instead, after choosing the type of grenade you want to use, you need to just hit left on the d-pad one time, rather than holding it as before. By just pressing left on the d-pad, an orange trajectory line will show up that you can then aim with to throw the grenade.
Grenades are very useful in The Division, so it’s wise to learn just how to best use each type for each situation you may face in the game.
