If you didn't get to join The Division closed beta, which is still running at the moment, then you will have another chance to play it in a few weeks. According to Xbox Italy, The Division will get a open beta later this month.
Looking at the leaked image from Xbox Italy, we can see that it reveals that the open beta will take place from 16th to 21st February. Just like in the closed beta, the open beta will be exclusive for Xbox One players during the first 24h.
Tom Clancy's The Division releases worldwide on the 8th of March on PS4, Xbox One and PC.
