Grenade Launcher

The Grenade Launcher is the 14th weapon available for purchase, costing and is unlocked at level 21. The Grenade Launcher packs 6 hand grenades that have a 3 second timer each, dealing very high damage but at the expense of short range before exploding. It also has moderate Accuracy and Agility.

Strategy
The Grenade Launcher may be short ranged, but this can be countered by changing the trajectory of fire, preferably at a 45 degrees angle. If aimed and fired correctly, it can wipe out enemies with lethal ease due to the extremely high firepower of this Weapon.

Unfortunately, this explosive Weapon is not built for close combat, as you can get injured by the explosions. In addition, if your grenade reaches your opponent too soon, there is a possibility of it ricocheting off your opponent and killing you instead. It is also advised to not purchased this Weapon (unless you've bought the + Reload speed in rifles perk) since it has a gruelingly long reload time, one of the worst in the game, so it is advised to always reload otherwise you may be caught off-guard.

Nevertheless, this is a great Weapon as it can easily catch enemies by surprise and they will not be able to escape easily. When used with skill, it can take out extremely far away opponents, and is even able to pressure players with better Weapons.

Trivia

 * It is able to fire grenades while reloading, like the Shotgun.
 * The Grenade Launcher appears to have a leaf-type sight, perfect for lobbing death angels over obstacles.
 * During the update Road To Glory the grenade launcher got a new skin which paints the grenade launcher red.
 * The skin makes a return in the Salute Our Troops event as a prize on tier 2.
 * Without the perk, it has the slowest reload for a Weapon that reloads one at a time. If you timed it, it is the slowest to fully refill the magazine.
 * Intrestingly, the scope cannot be used. Even if it could be used, it would be useless as the projectiles would explode in the air, or not go to the desired target.
