Hydroplant Hat

The Hydroplant Hat is a wearable item found in Abiotic Factor. It is most notably dropped by Zombies wearing a Hydroplant uniform in the Dam Structure of the Hydroplant, above the flooded Robotics Workshop. It can also be found in the Reactors, in the Dusk Reactor area, inside the bathroom on the second level of the section with many office cubicles and desks.

Because it is tied to specific enemy and location spawns, the hat is best acquired by thoroughly checking those areas rather than relying on general loot. The Hydroplant uniform Zombies in the Hydroplant are the most direct source, while the Dusk Reactor bathroom provides an additional fixed pickup for players exploring the Reactors.
