Whoever coined the phrase "Bang for the Buck" must have had this lovely thing in mind. Cheap, dependable, and utterly devastating.

About

The 40mm Portable Grenade Launcher is the default secondary weapon for the Engineer. It is a man-portable grenade launcher adorned with various metallic bracings and wires. The PGL is a break-action launcher, meaning that the gun's barrel opens on a hinge downwards to load in new grenades.

As far as DRG's arsenal goes, the PGL is as simple as it is effective. Find a tight cluster of enemies and pull the trigger, then watch as their gibs paint the cave walls. The PGL's high damage and decent blast radius makes it an excellent ground-based crowd control weapon, particularly against lightly armored foes such as Glyphid Grunts. It has a high Fear Factor, meaning that anything which somehow survives the explosion will be left fleeing in terror.

The PGL's biggest drawback is its low ammo count; the grenades are heavy, and as such the Engineer can only carry eight in reserve. As a result the PGL's immense damage must only be used when necessary and shells cannot be fired haphazardly. Certain modifications and Weapon Overclocks can help to mitigate this issue, but only by so much. The PGL also suffers to hurt bigger targets such as Glyphid Praetorians due to the lack of direct damage caused by the payloads – that said, the PGL is pretty good at breaking armor with a natural 50% damage bonus against it.

Unique Modifications

Incendiary Compound

Icon Upgrade Heat

Incendiary Compound is unique in that it causes the weapon to lose 50% in both Direct and Area Damage; unlike the "Lead Storm" Powered Minigun's Hot Bullets and Jury-Rigged Boomstick's White Phosphorous Shells. In replace of the lost damage, the grenade shells will instantly ignite enemies.

Proximity Trigger

Icon Upgrade Special

Proximity Trigger changes the projectiles of the PGL so that it does not explode on contact. Instead, it will bounce off surfaces and preserve velocity. When the grenade is close to an enemy it will automatically detonate. The trigger radius is based on the explosion radius, therefore a larger radius will cause the grenade to be more volatile. There is a very brief period of time directly after being fired in which the grenade cannot be triggered. If the grenade is not triggered within 3 seconds of being fired, it will automatically explode. The scaling damage of this upgrade is currently bugged.
