Defensive Microbots

The  are a new item in Risk of Rain 2. They take the form of a small mostly-spherical robot that hovers around the Survivor; this robot uses a point defense laser to shoot down incoming projectiles. It can intercept most (if not all) projectile-based attacks (such as Lemurian fireballs) but can be overwhelmed by large numbers of attacks, and is incapable of stopping hitscan and melee attacks.

The Captain receives one set of Defensive Microbots at the start of each run as part of his Passive skill of the same name.
