Which MTX gives the kill streak UI?

We're double checking if there's any additional microtransactions other than the Glorious Helmet as @ABVT mentioned. :)

After hearing back from the appropriate team members, it would seem that the Eldritch Hunger Armour from the Eldritch Hunger Supporter Pack provides the UI you're looking for.
