Steam Key not Working

Games Halo Infinite
1

I got the email today and I attempted to use it on steam and it says the steam key is a Duplicate? It’s for the “HALO INFINITE MULTIPLAYER TECHNICAL PREVIEW.”

It says active on Halo Insider Acc… first time i’ve used the key. Anyone else having the same issue?

Yep, sorry OP. The flights for Infinite were. Over the last 2 weeks and have since closed.
