Shark Invasion is a new part of the normal gameplay loop. During Shark Invasion, enemy sharks will spawn in your game introducing a new challenge.  

How does it work?
The new enemy sharks will appear in random places on the map, and they can either chase you, run away from you or engage in battle, depending on their level.

Are the sharks in Shark Invaders controlled by other players?
Shark Invaders are a new type of enemy with a brand new behavior, they represent other players in the game but they are controlled by AI.

Will I be able to see my friends in the game?
Not yet. This is a brand new feature and we are still working to improve it so you can see your friend's sharks in the future!

I don't want to get invaded. Can I turn it off?
Of course! You will find the option to turn it off in the settings.
