History of Calculated Trajectory

Calculated Trajectory is a Crucible weapon medal: in a single life, defeat three opponents with Grenade Launcher final blows.

How to complete

1. Equip a Grenade Launcher in a Crucible playlist. Suggested options include Colony, Fighting Lion and Anarchy.
2. Get three final blows in one life (no dying between them). Modes that make multikills easier include Momentum Control (when available), Iron Banner and Mayhem.
3. Tip: camp the heavy spawn and, once you have heavy ammo, stay put until it is spent so no heavy shot is wasted.
4. Progress is tracked under Crucible > Medals > Weapons (second page).
