There are lots of potential upgrades in Cyberpunk 2077, and finding the ones that work for you will vary from person to person.
The only way to know for sure whether or not something is or isn't for you though, is to actually test it out.
That means you need to know how to get everything.
Well, the good news is that we're here to tell you how to get your hands on/in the Projectile Launch System in Cyberpunk 2077.
How to get the Projectile Launch System in Cyberpunk 2077
The first thing you need to know is where you can actually pick up the Projectile Launch System.
You'll need 20 Street Cred before you can do so, so make sure you go out and strut your stuff around Night City for a bit before heading there if you don't have that yet.
If you've got that covered, you'll need to go ahead and find the Ripperdoc in South Watson, which is near the Bradbury & Buran fast travel point.
One there, go ahead and talk to Viktor and you can then buy the system for 21,000 Eddies. Make sure you then get the Ripperdoc to install it for you.
How to equip and use the Projectile Launch System in Cyberpunk 2077
Once it's installed you need to actually equip it, so go into your quick access menu, select the grenade slot, and then find and equip the weapon.
You can then use it by hitting the grenade button, but you can also hold the button to charge up the attack to do more damage.
It's a powerful weapon with a lot of different ammo types to utilise so that you can use it in a lot of situations.
