Alerts With "?" Reward

[Endrance]

Since this isn't actually a Alert warning ingame, but a doubt, i'm gonna put it here.

 

I have a few questions about alerts, here they go:

 

1st. Does the Alerts appear randomly? Or from time to time (like every 30 minutes).

 

2nd. Does "?" Reward alerts appear randomly when a alert "spawns" or once again, from time to time (like every 2/3 normal credit alert, a "?" reward alert spawn).

 

3rd. Is there a list of possible rewards? I know there is the blueprints of Orakin Reactor/Catalyst, some warframes and warframe helmets (if not all), dark sword. But only those? Or more?

 

 

ATM i believe this covers all i "need" to know.

 

Regards, and happy hunting.

Your friendly Tenno, Endrance

1st: Random

 

2nd: Random appearance

 

3rd: Every item can drop. But I think orokin stuff is special in some ways. But all the other stuff can drop. skins, weapons etc

A ? is usually an artifact or a blueprint for a weapon / helmet.
But i do not know what happens if you do the mission whenyou already have the item, you get it a 2nd time? or you dont get it at all?

If you get an Artifact you already have it won't change anything but if you get a BP you already have you will simply have 2 BP's

Go to the WarframeAlerts twitter page and it tells you what the rewards are for the alerts they post. Helps if you need something in particular.
