This is the Marauder from The Cycle: Frontier video game in the form of a statue for display!
Enjoy!

Trivia:

Jeff got its name on the 22nd of June in 2021, when a Discord moderator named cc_Stalker_Ente got stuck on a rock below Skeleton Observation site for 30 minutes surrounded by 2 Marauders. Stalker used up all her ammunition trying to kill the Marauders, but then the storm began. While waiting out the storm Stalker watched an episode of the cartoon "American Dad" and decided to name the Marauder after "Jeff Fischer", one of the main characters of the show.

The name then spread throughout the players of Closed Alpha 2 and was commonly used during that time. At one occasion, one of the community managers had to explain to the developers who Jeff is. The name was spread further when a community member told Summit1g (a popular Twitch streamer with over 5 million followers) on stream that the Marauders are nicknamed Jeff. Summit1g used the name, and it has been in use ever since.
