Atlas EX Gunblade Campaign...

I did two Recommended quests today and I didn't get the gunblade. It doesn't say we get it at a later date, so what am I not getting? Why do I not have it?

This is like the 3rd thread today on this topic

Although it doesn't say it on the website - but in game itself shows you need to do a total of 5 recommended quest for the campaign.
