How to Use the Grenade Launcher
How to Obtain the Grenade Launcher

The Grenade Launcher is a normal drop. It's an attachment with a very low drop rate, and you often can't find it even after searching an entire town. Since it's a valuable item, prioritize finding a compatible rifle when you get one.
Load Throwables from Your Inventory

You can load all types of throwables as ammunition for the Grenade Launcher. One throwable equals one shot, so you need to gather plenty of throwables beforehand. To load the first shot, manually load it directly from your bag.
Effect of the Loaded Throwable Occurs
The Grenade Launcher can trigger the effect of the loaded throwable at the point of impact. Smoke grenades create smoke, flashbangs create a flash, and frag grenades cause an explosion. Note that the power of frag grenades is reduced!
Cannot Fire Immediately After Picking Up

You cannot fire immediately after equipping the Grenade Launcher or if you've run out of throwables. Reload and gather throwables frequently. Reloading takes about 4.5 seconds for any throwable.
Aim and Fire

Once the Grenade Launcher is equipped, you can fire by tapping the dedicated button. If the mark is red, it means you don't have a grenade or it's not loaded, so check.
Performance of the Grenade Launcher
Automatic Reload from the Second Shot Onwards!
If you have spare throwables, the next round will be automatically loaded after firing a grenade (throwable). Automatic reloading after firing takes 4.5 seconds, and once loaded, the next round can be fired immediately.
Short Motion and Easy to Handle
The Grenade Launcher can fire a round instantly when the fire button is pressed, making it usable anytime and less prone to leaving you vulnerable. It's more accurate and has a shorter motion than throwing a throwable normally, so utilize grenade (throwable) launching during engagements.
Grenade Launcher Button Not Appearing?
Check Button Layout Settings

If the fire button doesn't appear even when the Grenade Launcher is equipped, try checking your button layout settings. Be careful, as you won't be able to see it if the opacity is set to 0%.
Conclusion on the Grenade Launcher
Short Motion and Excellent [Important]
The Grenade Launcher has no drawbacks; although its power is low, its short motion makes it easy to use and excellent. Its use differs from hand-thrown throwables, and it's useful when you want to immediately follow up on an enemy trying to hide during an engagement.
Evaluation of M27 and M16A4 Increases!
The Grenade Launcher is a very excellent attachment because it has no drawbacks and enables powerful grenade launching. The value of the M27 and M16A4, which can be equipped with the Grenade Launcher, increases further.
