This trick works for primary weapon only, at least that is what I have
found.
First, set your multiplayer weapon preferences up.
Then, when you have the desired primary weapon chosen, go back and
select single player. Choose your mission, but do not press the right
and left arrows next to the primary weapon on the weapons confirm
screen.
While the mission loads, the bottom of the loading
screen will say you have the default primary weapon, but when the
mission loads, you will have the primary weapon you have chosen. |
