World of Warships: Legends

I completed this using the Orion Tier III British battleship with HE shells. HE shells will help because the damage continues as long as you set fire. Try targeting enemies that are out of your allies range as they will try to steal your kills at the last second. Use islands as cover and don't keep yourself in the line of fire of multiple ships. Depending on the enemy ship type you may have better or worse luck with more evenly timed single shots versus full salvos. This will take a bit of luck and patience to get. Good luck.
