I've got it, but my friend (Harry4000) hasn't, despite having 1000G+ and I discovered, that to all who read; YOU'RE GOING TO NEED THE META - GAME POINTS.
It should be really easy to get now with all the new achievements. I don't have all of the original achievements but I got the Katana by getting most of the Legendary achievements. It's definitely worth it seeing as it is very easy to get now.
