Sgt Johnson Firefight

Anyone out there know if sgt Johnson is usable in firefight through the preorder card from odst? Looked around myself couldn’t find anything.<!–Session data–>

I’m pretty sure that was an ODST exclusive man. You can get his voice in Firefight, but not his character. Kinda annoys me, he should have been carried over as a choice if you pre-ordered ODST imo.
