Mass Effect 2/Infiltrator

When you need someone deep behind enemy lines, there's only one person for the job—the infiltrator. Armed with a long-range rifle, infiltrators can neutralize targets before moving into the combat area. These special agents combine the best of a front-lines soldier with the technical cunning of an engineer. Once behind the enemy's front line, infiltrators can use their tech abilities and special munitions to take care of nearly any foe. If things get too heated, infiltrators can even activate a tactical cloaking device, allowing them to escape or setting them up for the perfect headshot.
