Straight from the main menu, we can access the account tab. We can find a lot of useful information in there, such us the rank system and the ways to obtain money in the game. Let's look closely on the whole tab.
1. In the top left corner, we can find the current level of our profile, the amount of experience required to next level (we earn it during battles for various actions and for the final result), our rank and also our division. The last feature (mainly because of the fact that the game is not in its final version) is not yet active, so we cannot create any guilds, which in this game will be called divisions.
2. To the right, we can see the amount of credits we have (Gold and two other resources - Platinum and Valor), the number of soldiers we can use and the ranks that we've already unlocked (both elements are obtained when advancing onto higher levels). We can also see the range of effect of our skills/items, which also rises when we level up.
3. In the top right corner we can view information about the time spend playing the game, the number of victories and also the victory - loss balance.
4. At the bottom, we can look at a different system of advancing, which applies only to our money. These are ranks from E to SS, which we obtain as we earn experience points in the game (we gather experience for both the leveling systems, but they require a different amount of it). Their only use in the game is that they increase the amount of gold obtained for every hour in the game. It is the only way in which we can obtain gold, because Platinum is bought for real money and Valor is obtained for unlocking achievements and logging in to the game regularly (there is a nice reward for logging in every day).
