Battle points represent your strength online. This number fluctuates up and down as you lose and win matches. Reach a certain number of battle points and you can be promoted to higher tiers.

If you have earned more than a certain amount of battle points by the time a new season starts, your points will be reset to the maximum point cap. For more information on how this works, see the notifications posted for each season.

Confirmed Issues:

・In versus mode, while in the middle of a battle, players suddenly lose the match.
・All viruses were eliminated, but new viruses do not appear.
・Even as time has passed, blocks do not appear from above and so the area does not get smaller, making it impossible to win or lose.
