When using a fast attack vehicle the machine gun often gets low in ammo. Is it possible to reload the primary weapon?
The primary weapon cannot be reloaded. If you want to refill your ammo you will need to shoot out the remainder of the ammo in the clip.
This will unfortunately reveal your location on the mini map, but often this doesn’t really matter much. You can usually get away with your location being revealed and no one will attack you.
If you shoot off the rest if the ammo in the clip it will trigger the auto reload which will be better than running into a battle with half a clip left of bullets.
