Bipods for snipers : add the possibility to select bipod accessory the player will have to extend manually before snapping it (grabbing one leg for instance) onto a surface to increase aiming stability especially for long distance targets but also easier to reload bolt snipers (as the front hand pivot would be the bipod's instead). Also if the user didn't fold the bipod while moving, the extended bipod would add a bit more inertia when moving and make it harder to keep a steady position or aiming while standing up. When the bipod is snapped onto the surface, the user can't use anything else and have to "unsnap" it before.
