For those who are not sure how to enter the promo codes, there are two ways that I'm aware of.

1. If you are in game, pull up the chat and type /promo xxxx, replacing the xxxx with the code.

2. The second way is from the sts nexus.

Tap the STS Nexus button from the character screen:



Then tap the promo code button in the lower right corner:



Then just enter the code and collect your phat lewtz.
