Aquarium MM2

Aquarium is a Legendary gun from the 2025 Summer Event, painted as a bright blue ocean full of colourful fish. Its partner, the Aquarium knife, came from the 2025 Summer Box for 800 Beach Balls rather than the battle pass. Tier 24 of the 2025 Summer Event battle pass, whose tiers cost 800 Beach Balls each; the wiki puts the total to reach it at 18,400. Trade-only since the event ended.
