Dan am now having trouble doing missions the need arties . be cause of changes in the game some missions i can not longer do cause i do not get the arties i need in my drops and cause i donot higher npc's i donot get those arties for the missions .second issue i did the netflixs free month too get the Fb credits and never got them .if you can help it would be great.

What missions? If its for Exotic/Dyson/Rift then you will just have to do A lot of NPC hunting or buy them , there to good to just give away.

For the facebook offer you have to take that up with facebook.

please tell us what missions you're unable to do, and what artifacts you are unable to find....

if the amount of arties that i am having issues with ,each mission that needs arties like the terraforming needs 10 of them and i have never even seen one.then you have those the need grav-whip traps and i am lucky if i even get one a week off my artie drops. the same goes for containment missiles ,TM's. what i am trying too say is cause of the changes in the game it is getting hard too do the missions.and cause of the limited amount of income . i am unable too do the mission that need these things. i have tried too do the free earn Glpoints stuff . but alot of it just does not work for me .so what i am asking is if the mission are done in order will it open more of what i need too complete the game?

for the missions that don't require the terraforming devices, I get them almost every day from my arti pulls, I have 1731 artifact points an hour, I'd suggest you get at least 1500 artifact per hour.
for the terrafomers, the NPCs that drop them are the dark scrap carrier (since you need contaminant missiles for a mission, i assume you have the crimson cluster project unlocked and therefore you have traveled out of the dark scrap carrier's rank range.) and T.O. troop carrier (yet I remember very early on getting one from a dark scrap transport), those NPCs are rare so you'll have to do some NPC hunting to find them, especially the T.O. troop carriers.

well.. first let's address the terraformer issue...

.......if you don't feel like buying them, then go kill lots of NPCs... because you'll be wanting to find the rare spawn T.O. Troop Carrier...
(and just wait for the TWO missions that follow that one... you'll spend several years killing troop carriers looking for 40 of the elusive Quasi Spacial Expanders)

don't worry.... other missions aren't that tough.... it's just that this particular line of missions gives you your 5 invincible mission planets.... one exotic, one dyson, and three rifts

------------------------------------
now.... as for the other missions.... go increase your artifact production.... you're just starting to see missions that require artifacts... there's many more.... over time you'll collect vast quantities of these artifacts and the missions will no longer seem as burdensome....

....by the way... i'm only lvl 535, and just a month ago I finally completed the crimson cluster missile mission.... and a few months prior I completed the mission that needed the grav-whips

don't worry so much about what you can't do... just do what you can.... in time it will all be a piece of pie..... or blueberry cheesecake....

thank you ya'll have been helpful in this issue of mine.
