The S. S. Devastator is a Hardmode gun that is dropped by the Submerged Mimic. It occasionally shoots special rocket projectiles in addition to bullets, which home towards enemies and explode to deal damage in a small area-of-effect.
- It can be considered an upgrade to the Shark Storm.
- The ability to fire homing rockets is similar to the vanilla weapon Vortex Beater.
- S.S. stands for Shark Storm, but also mirrors the stereotypical S.S. prefix for seagoing vessels.
- Similar to the Shark Storm resembling a Sharkron, the S.S. Devastator resembles Duke Fishron itself.
