Unknown imperial helmet replica specifications

[kniebolo]

Hi, could you recognize this imperial helmet replica and tell me what type of Star Wars character it represents exactly?
Is here someone who can re-create it?
Thanks

I think it's from the game Jedi Outcast. It's a Shadowtrooper which was basically a Stormtrooper that can rudimentally use the Force. The one picture is labeled Cosplay Kingdom Studio, so I would start there.
