History of Bonus Focus I

Bonus Focus I requires attaining 5 Bonus Focus drops from Focus activities (progress 0/5).

How to complete

1. Open the Portal and look for activities showing a specific gear icon (weapon or armor, not a green engram) in the bottom left. That is the Bonus Focus; it rotates regularly and only applies to certain playlists.
2. You get one drop of the featured item for your first completion of that activity each day. Later runs the same day only have a chance, improved by a higher grade.
3. Aim for performance grade B or higher.
4. Complete five such activities (five drops). Quickplay is suggested by one guide as a frequent source, though a Steam thread reports that matchmaking playlists may not count for tracking on the related Fireteam Ops objective.
