Campaign - Dieing Out.

Uncommon Infected: Gun-Wielding Infected. They has 100 more health then a normal common infected, and wield guns that do 5 damage on Easy, 8 on Normal, 10 on Advanced, and 20 on Expert. The guns fire every 2 seconds. They crawl on all fours, making them extremely slow.

Story: The Left 4 Dead 2's rescue from the end of The Parish, as always, has crashed right out side of a old military outpost. When inside, it has been overrun; according to signs inside, it was in fact the Military outpost that the survivors were supposed to be taken to. However, some of the Military have control over their self conscious after being infected, becoming the Gun-Wielding Infected, now seeing all Infected as their comrades and the Survivors as infected. After making their way through the base (which takes up 2 chapters), they make it to the outside, finding themselves in a highway. This is where things get hairy.

New Special Infected: The Runner. These infected are 6x as fast as the normal common. They has 500 health; when they reach a survivor, they grab on to their back, becoming a ticking time bomb. If not killed within 5 seconds on Easy, 4 on Normal, 3 on Advanced, and 1 on Expert, they do 5 damage on Easy, 10 on Normal, 15 on Advanced, and 25 on Expert. Playable.

NOTE: They only appear on the third and fourth level of Dieing Out; on all other campaigns, they appear everywhere.

The Survivors now traverse the highway, having to deal with the Infected along the way. The Highway takes up the third and fourth levels. The finale is taken place at the end of the highway, where the survivors are faced with a metal wall about 30 feet high, where on the other side is a military outpost that is still standing. The left, right, and upper walls are taken up. However, they find a radio on the ground, contacting the military outpost, saying they shall send their helicopter, however do to all it's trips, it will take 10 minutes to fill up the gas tank. Due to the noise the tank makes, it attracts the Infected. Luckily, the military is assisting them, having two miniguns up on top of the wall, being manned by two military units. After rescue arrives, the survivors finally made it.
