And even then it DOES look pretty huge--the base of the gun stretches 3/4 of the way across the bottom of the screen and that's only half the gun showing (it really only shows starting from those coil things on top of the gun).
In third person, it looks a little smaller in Doomguy's hands because he's a huge beefy space marine instead of two out of shape nerds, but it's still clear that this is a massive fucking gun.
