Where it sits
The close-range primary. This is the slot for routes that are too tight to hold a lane, where an assault rifle is more gun than you can point. The Vault Edition's Signature Weapon Collection also includes a ISO Nightshade blueprint called La Sombra Venenosa, which is a cosmetic variant of this weapon rather than a separate one.
How to unlock it
ISO Nightshade becomes available at player level 4. Create-a-Class itself unlocks at player level 4, so this is one of the later weapons in the progression rather than a day-one option. Use the unlock tracker to see exactly what else your current level has already opened.
What to test
Test it immediately after a sprint, which is when a close-range primary actually gets used. Change one attachment at a time and keep notes — a change that feels better is not always the change that performs better.
What is not published yet
Activision has not published damage, range or time-to-kill figures for the launch arsenal, and this page will not invent them. Any ranking you see elsewhere is a guess until the game is in your hands and you have measured it yourself.
