If you hurry you can still pick up a beta badge (which does what? lol).
“When Tribes: Ascend officially releases on April 12th, all Beta players who have reached level 10 will receive an exclusive in-game Beta badge.”
If you haven’t played the game yet and want to play a competitive game here’s your chance. Definitely try it out. It’s free to play so it won’t cost you anything except for some of your time. This is an old school CTF style game. Definitely recommend it.
Note that anything you unlocked in the beta will remain unlocked once the game goes official.
