I created this based on an old Rust concept from their concept limbo repository. I liked the .50 Caliber turret idea, as something like a tier 2 turret. But it would probably be too powerful to be implemented into the game. I would like to retopo and paint this like an in-game model in the near future.
Many thanks to Zoltán giving me feedback https://zoltanh.artstation.com/
Have a nice day!
