Proteus is one of the two brand new battle cars released in the Aquadome Update. Currently, you can obtain the car by purchasing it as DLC. From the darkest fathoms of the ocean, Proteus is considered as an imposing deep-sea diver which is created to handle the pressure excellently.
With the following premium decals, you can use anything to equip for the Proteus without difficulty. They are Crash Dive, Cuttle Time, Fathom, Ladybug, Tiger Shark, and Stripes. Aside from that, you can visit the Black Market to get much more.
Many people often compare Proteus with Triton. Both are fairly weird on the sound front. In which, Proteus is especially troublesome. Besides, they have really awful skins. You may want to test them without any decal. On balance, we expect you will prefer Triton. They need to own more characterful and embrace the steampunk or go further with sci-fi sides.
