Probably Engine Limitations
And there should have been sound differences in space, not a big deal bit with no air in space sound travels differently
And also firearms don't work in space, we went over this in COD:Ghosts
I know its nit picking, but it could have been a little more immersive
Still a cool level though, also low gravity PvP when ?
Sound doesn’t travel in space…at all.
Energy weapons and kinetic certainly could fire in space. Energy weapons like lazers and light don’t require a medium. Kinetic rounds carry their own oxidizing agent. They would work even better without air resistance to slow them down or gravity to make them drop.
