Sometimes, you just want to shoot terrorists until they're dead. And not in a careful and methodical way where you inch along a grassy field towards a ridge where you use your IR goggles to locate them, so you can fire your SXHXZZZZ-XIII (DU) through their left eyeball at a range of forty kilometres. No - instead you want to run right up to the blighters and tw** them with your big old samurai sword. Take that! And that! And that!
