Hello!
We were just told by willondiscord/serbaingamer that Blast Rage Online is still playable. You just have to follow these steps:
Just click on the settings at the bottom where the red arrow is pointing to, then click North America (might try Europe if you’re from Europe), then enter in your username/password.
