Final Salvation mod for Left 4 Dead 2

Final Salvation is a Left 4 Dead 2 campaign created by an international team of developers. After travelling along the river for a few days, the four survivors tie their boat to a small dock along a canal in an unknown city. They are drawn here by radio messages indicating a possible military controlled outpost within the city. As they move deeper into the city, the military's plan becomes clear. Their only hope for salvation is to reach the outpost. They need to move fast, because when the clock stops ticking, the worldwide bombing of infected areas begins.
