Explosives tend to be seen as a last resort, but that should not be the case in this game. They are not that costly and they can often be worth the expense by saving your armor from getting trashed.
Any time a group of enemies is in a very tough position to attack, consider using a grenade instead of struggling and taking a lot of damage.
Even if the grenade doesn’t hit the enemies, it will usually force them from their coveted position and allow you a lot better odds for taking them down cleanly. There are numerous types of grenades that are suited for various situations, but they are all effective for dealing with hard-to-hit enemies or large crowds. A gas grenade is great to use indoors to force enemies to flee or suffer its toxic fumes.
Smoke grenades create a wall of thick smoke that reduces the enemy’s sight. It can be used offensively to blind your foes and give your mercs a chance to cut them down. Also, grenades can be used more passively or as a defensive maneuver to allow your squad to sneak past foes or retreat.
Stun and flash grenades can be used to stun enemies, making them extremely vulnerable. The only downside to these explosives is that they can affect your mercs, too! The last type of grenade is the frag, which causes damage over a large area.
It is a great tool that can damage multiple foes at one time. These are one of the most powerful items you can carry, and all your mercs should have them at their disposal.
