Borderlands 3 has 10 of Zero's Targets of Opportunity Locations. This guide shows where to find and defeat all of them to unlock the Zer0ed In trophy or achievement.

None of them are missable! You can still do everything after the story in free-roam.

Targets of Opportunity count as a Crew Challenge (type of Collectible). On the map they get marked by a green icon when going near them. Completed targets change to a slightly transparent icon. On the world map you can press D-Pad Right to see how many targets you've completed in the area. There's never more than one per map.

You also get a mail with a free weapon after every hunt. You can retrieve this under Pause Menu > Social > Mail. Completing all 10 targets of opportunity gives you a legendary sniper called "Vicious Lyuda" (and it's a pretty fantastic one that has a quick-shooting barrel like a minigun). If you want, save the last target until you're level 50. Then the legendary reward also scales to level 50 or whatever your player level is.

This guide shows all targets of opportunity . If you haven't been to an area yet just ignore it till you've finished the story, then you'll have access to everything.
