An Account's Rank in Antwar.io is directly related to how much you, the Player with the account, play Antwar.io. To access the Rank feature, you must first have a valid account. Then, as you play, you will gain XP (Experience). If you get enough XP, you level up.
Creation[]
If you are playing without a valid Account, you will still receive XP, but it will not count towards leveling up since you are not able to be leveled up without an Account.
Uses[]
The main use for your Rank is to show off how much you have played Antwar.io. It will also increase the likelihood of you being able to join other higher ranked players. If your Rank is high enough, it is displayed on the Leaderboard.
