Hydraulic weapons are an event exclusive weapon set granted to those who participate in the Mutant Storms event. They boast a yellow and black appearance with white accents. Hydraulic weapons have high impact and knockback but at the expense of low fire rate and reload speed.
Schematics for Hydraulic weapons can be obtained by cashing in 1000 Storm tickets for a Storm Llama while the event is active. The Hydra assault rifle can be obtained via purchase of the Transform Key in the Event Store for 1,680 seasonal gold
