I chose Memory of Timur to get me some alien friends.
Why is it dangerous? The effect ends after 30 seconds. Better keep that in mind or you might end up getting shot in the back and killed in heroic strikes, nightfalls etc.

I went with the Memory of Timur. The concept of having an enemy turn ally for a few seconds just sounded so cool to me. I'll get the others eventually, but I might hold off on buying anymore this week to see what ones we can get next week.
