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. Community suggestions include Colony, Fighting Lion and Anarchy.
2. Get three final blows in one life (no dying between them). Modes that make multikills easier, per community posters, are Momentum Control (when available), Iron Banner and Mayhem.
3. Tip from the Steam thread: camp the heavy spawn and, once you have heavy ammo, stay put until it is spent so no heavy shot is wasted.
4. You can track medals in Triumphs > Crucible > Medals > Weapons (second page).

Seal / reward

The medal was needed for Season 5's Mountaintop quest ("In Pursuit of Honor"), reportedly 75 of them. Check the player counts against current game data; this was Season 5 information and may be outdated. No seal confirmed.
