MattleFun v3.9.0 has been released with new gameplay improvements, a new ability, and extensive monster rebalancing. The update introduces Penetration+, improves boss tracking with directional arrows, and increases monster spawn rates across different stages.
What's New in v3.9.0?
New Ability: Penetration+
MattleFun v3.9.0 introduces the new Penetration+ ability with two upgrade levels:
- Level 1: Ignores 50% of enemy armor
- Level 2: Ignores 100% of enemy armor
Penetration+ gives players a new way to deal with heavily armored enemies by reducing or completely ignoring their armor.
Boss Directional Arrows
A new directional indicator has been added for bosses located outside the screen.
The feature includes:
- Directional arrows displayed alongside boss avatars
- Arrows move around the boss avatar to accurately indicate the boss's direction
- Supports multiple bosses simultaneously, including the Mini Boss and Final Boss
- Automatically hides when a boss enters the screen
- Disabled in Blackout Mode
This makes it easier to locate bosses even when they are outside the visible gameplay area.
Red Potion Improvements
The Red Potion duration display has been improved to provide a clearer and more user-friendly experience.
Increased Monster Spawn Rates
Monster spawn rates have been increased across different stages of each match.
This change introduces more frequent enemy encounters and increases the intensity of gameplay.
