Helix Cannon
Hold to charge a plasma bolt, let go to fire. The longer the charge, the harder it hits and the bigger the blast. The Helix Cannon is a prototype-grade heavy in Squadbreak that any class can use as a primary.

How to get it
The Helix Cannon only drops in missions, from gun cases (amber) dropped by enemies, bosses and mission wins. It can drop once you’re level 17 or higher (gear more than 2 levels above you never drops), and you can equip it from level 19: until then it waits in your Inventory, locked. It belongs to the character who found it.
Prototype is the grade rolled on 0% of drops on tier-1 maps, 0% of drops on tier-2 maps, 8% of drops on tier-3 maps, 20% of drops on tier-4 maps, and 35% of tier-4 boss drops. See loot and drops.
A gun you already own is scrapped for gold when it drops again.
Upgrades
Spend gold in the Inventory to upgrade each part up to its grade’s cap. Taking every part to the cap costs about 201,540 gold. An Augment Core plus gold then pushes a capped part 2 levels further at 1.5× strength.
