Call of Duty BO3 Shadows of Evil

[False]

The achievement I'm trying to get is called "Packing Early". It's one of the new secret achievements for Black Ops 3 Shadows of Evil Zombie game. Looked online for this but nothing so far, seeing if anyone knows how to get this yet. The way you get this is by doing all rituals by round 1. I've only been able to complete all fIve rituals by round 3.
