The earned credits displayed on the Battle Results screen are your earnings before things like ammo and service costs are taken into account. As you move up, the ships become more modern, fast, and powerful, all the way up to the Legendary Tier, where you get to experience the ultimate naval machines.

From that point, you're free to continue with whichever type suits you best, as well as pursue other Tech Trees.

Tier III will allow you to try out the battleships, which bring huge salvos and armor but lack maneuverability.

From there, you'll be able to branch out into the destroyers, which are all about stealth and high risk, high reward gameplay. These are faster, better armed, sturdier and have a choice of armament (high-explosive or armor-piercing shells, except for some British ships). After playing several battles with the starter ships and becoming acquainted with the controls and basic mechanics, you'll move up to Tier II cruisers. Overall, tiers can be separated into two distinct timelines-Tiers I–IV belong to the 'dreadnought era,' while everything from Tier V and above consists of WWII ships. You begin at Tier I with late 19th to early 20th century cruisers.
