Allows players to pick up Special Weapons

For the sake of this argument, Special Weapons refer to weapons that one can picked up. For now, this list is limited to the Sniper Rifle albeit I'm sure more items will be added in the future.

Say you're playing as a guard in Riverside, and you're spotting for a sniper next to you. Suddenly, a you hear a shot and besides you lays your companions dead body. In a scenario like this, you should be able to pick up their sniper rifle and continue sniping as opposed to currently where you can only view the sniper in their hands.
