While working through Once Human, you can unlock several armor sets and blueprints. These are crucial to your survival as each has a distinct set of bonuses when worn by your character. Those who want to play snipers are likely after the Renegade armor set.
Like many of the armor and blueprints in Once Human, the Renegade armor set is only available from a specific activity. You’ll need to focus on this if you want to have a chance to earn enough pieces to unlock it. But unlocking every piece could take a lot of time, and you’re better off focusing on the critical ones you want. You only need at least four armor pieces to get every bonus.
