Brita's Weapon pack mod is probably one of the most used modification in Project Zomboid's latest build. This particular mod gives the player a whole new array of firearms to play around with ranging from small sidearms to long rifles and even heavy weapons that can take out entire hordes of zombies.
One of this such heavy arms is a grenade launcher that can be mounted to some rifles such as M4A1 and M16. It can fire both HE and incendiary rounds which can prove to be very effective in taking out large groups of the undead. But the question is how to use it.
This is a common issue among players who just got their hands on them. Well, it's quite easy. You just press the period (.) or comma (,) key on your keyboard to switch the firing mode to your attachment. Easy right? Now what do you do now that all of town heard the explosions? Switch back to your main shooting mode, of course. But how you may ask? Easy, press the Home key on your keyboard to switch back from launcher to your main rifle.'
That's it! You just learned how to use the grenade launcher attachment in Project Zomboid and I hope it will help you in your survival.
