What's New in Lionfish Hunter
1.11
October 29, 2026
A THICKER WETSUIT. The kit shop sells suit thickness now: a 5 mm Steamer that takes a quarter out of every sting, and a 7 mm Semi-Dry that halves it. It sits under FINS in the KIT tab. The spines are still the danger. The thickest suit never takes less than half a sting, so getting close to a fish is still a decision, just one with a bit more slack behind it. Your suit colour is unchanged and still lives in the wardrobe. Every existing save starts in the 3 mm Shorty, which is what you have been diving in all along.

FAQ
What is the main goal of Lionfish Hunter?
The main goal of Lionfish Hunter is to control the invasive lionfish population by spearfishing them. Players earn money from their catch to upgrade equipment and improve their ability to clear reefs, contributing to ecosystem health.
How does the spearfishing mechanic work in Lionfish Hunter?
Players pull back on the right side of the screen to load the speargun and release to fire. The spear has a tether, requiring careful aim as each shot is a decision. The location of the hit affects the fish's value.
Can you drown or lose your catch in Lionfish Hunter?
No, you cannot drown in Lionfish Hunter. If you run low on air, you simply surface. You also never lose your haul of fish, ensuring all your efforts are accounted for.
What are the risks of getting too close to lionfish in Lionfish Hunter?
Lionfish have venomous spines that can sting you. Getting too close to them, which is often necessary for a good shot, can result in a sting that costs you air and potentially a 'first-aid bill' within the game.
How does selling fish work in Lionfish Hunter?
You can sell your spearfished lionfish to a restaurant for good money, a rendering company for less, or decide based on the fish's condition. The restaurant pays well for whole, undamaged fish, while the rendering company takes anything.
What can I buy with the money I earn in Lionfish Hunter?
Money earned from selling lionfish can be used to purchase bigger tanks for longer dives, larger bags to carry more fish, better spearguns for improved accuracy, and a better boat to reach reefs further out.
Does Lionfish Hunter have ads?
No, Lionfish Hunter is ad-free. The game explicitly states 'No ads' in its description, providing an uninterrupted gameplay experience.
Is Lionfish Hunter available on all devices?
Lionfish Hunter is supported on iPhone, iPad, and iPod. It is designed for Apple's mobile operating systems.
