Trackers are small, ball-like DeeBees that use their body as a weapon, closing in on the player and exploding when in close proximity. They can sometimes drop a Bolo Grenade when killed. Shock variants are used when non-lethal force is needed.
Kicking a Tracker away will cause it to become inactive for a brief moment, though kicking it twice will destroy it. Inactive Trackers are easier to destroy, but will still explode when destroyed. If kicked into their allies, they can damage or destroy them.
