Along with a sniper rifle, the player can also carry a pistol, a submachine gun, and explosives. Some pistols have a suppressor so that the player can kill enemies without being heard, others do not, so the player must be careful when choosing his or her weapons. Submachine guns are best used in emergency close-quarters firefights, but the player must be careful not to waste ammo. Explosives can be used to lay traps for the enemy or protect the player from being flanked.
