I've only given this game a brief try so far, but I wanted to point something out I found really bizarre.
How come when you press the middle mouse button, the game goes into 3rd person, and your character is now suddenly a soldier in all green fatigues with a shot gun, a much higher polygon count compared to the aesthetic of the game, and is all around completely detached from your first person character?
Like, when I press the left mouse button, he still performs an action, but instead of swinging the knife or the axe, he like waggles his one-handed shot gun in front of him, like he's gonna beat something with the barrel.
