The Awakening mod for Unreal Tournament 2004

If you are looking for real zombie survival horror game this is your choice.

Inspired by zombie movies. We bring you The Awakening.

The Awakening is an immersive 3rd-person cooperative multiplayer experience that combines suspenseful action with nerve-wracking strategy. Players must coordinate their efforts against a common foe, instead of competing against each other, if they hope to survive. This combined with a compelling storyline will serve to bring together a tight-knit and dedicated online community.

Players take on the roles of civilians who have survived the initial zombie infestation and banded together to form a resistance group. Together, they must rely on their ingenuity and the sparse resources that are available to hold off hordes of enemies and look for a possible escape route from the city. Every day is a struggle to survive -- and every night is a showdown against seemingly impossible odds.
