Brutal Muscles
The evolution Brutal Muscles is a speed-enhancing, damage-boosting organ that can be put into one of the three slots of your shark in Maneater.
Unlocked by defeating the Infamy Level 10 boss, Captain Robert Brunlett, the Brutal Muscles evolution is a popular choice in the late game.
Brutal Muscles Official Description
“This evolution increases your swimming speed and the damage of your tailwhip.”
How to Unlock the Brutal Muscles Organ
To unlock Brutal Muscles, you’ll need to increase your infamy level to Infamy Level 10. To do this, just eat some humans and then defeat the hunters who come after you.
Once your blue infamy bar has been filled from Infamy Level 9, Captain Robert Brunlett will arrive near your location, looking to end the massacre.
Defeat Captain Robert Brunlett to unlock the Brutal Muscles organ and reap the rewards of 3,350 Protein, 3,350 Fat, and 3,350 Mineral.
Brutal Muscles Parameter Boosts
By upgrading the Brutal Muscles evolution to Tier 5 and equipping it to one of your shark’s three organ slots, you’ll then get benefit from its passive effects and the following ratings parameter boosts:
- +2 Damage
- +10 Speed
Ratings parameters consist of 20 segments, with each segment housing five points each. Applying an organ evolution that gives +5 to a rating will fill the equivalent of one segment.
