Players without a previously active SWTOR account can now play Star Wars: The Old Republic up to level 15 with no charge or time limit! You do not even need to enter a playment method. Furthermore players can now earn an in-game reward (Kurtob Alliance Speeder) for inviting your friends to take part in the 15 level trial.

All players who have already referred a friend through the Friends Trial and have had their friend purchase the full game, will be retroactively granted a Kurtob Alliance Speeder via in-game mail.
