Battle Attacker
The Battle Attacker fleet
The battle attacker is the starting fleet of the game. Since it got re-added, it currently contains Sailboat, Sea Monster, Kayak, and Raft. The fleet is described as "A great starting fleet with strong attacks". Winning 3 battles with the Battle Attacker unlocks the Rogue fleet.
Fleet Analysis
The fleet contains 3 attacking ships (Sailboat, Kayak, and Raft), and 1 scouter (Sea Monster). The fleet acts as a good introduction to the basis of battletabs, being that you can use special abilities to gain an advantage, with simple ability concepts. However the fleet contains no sonar or revealer ships, which are better examples of scouters than sea monsters, so it is recommended to unlock more scouting ships sooner to be available for use.
History
