I thought it was important to post the fact that Xur is finally selling one of the most wanted guns in the game, the Gjallarhorn. If you do not have it and want it, I reckon it is time to go ahead and finally acquire it. By the way, Xur is at the tower in the music area located underneath the future war cult representative. I suppose it is so guardians have some music to dance to after they finally acquire the Gjallarhorn. :)
