There can be only one

[Deleted member 471407]

Hmmm... Since others get it I don't really know. There should be no known problems. Are you doing some kind of special tactics?

Oh hai!

Not really.
I tried on single player adventure and online coop adventure.

I killed several times (by suicide and trying to kill again), first time with the sword, then with beams, thunderbolt, rocks, pushing him off the cliff, yelling "THERE CAN BE ONLY ONE" as he died...
Nothing worked.

Nor me nor my online friends got it when we killed him.

It should be working, so for now I can only ask you to continue trying. We will see what we can find out on our end however. Thank you for reporting this issue.
