help me to remember this game name

god hand maybe?

my first thought was left 4 dead but i cant fit the book into that one..

How was it graphically speaking? 3D or 2D?
What type of view? Isometric? Third person?

"Land of the Dead: Road to Fiddler's Green"

Kungfu Fists:
Damage: 30 x 5 (primary fire) / 100 x 4 (alt fire)
Speed: Very Fast
Range: Short
Hits to Kill (Zombie): 5 (primary fire) / 2 (alt fire)
Hits to Kill (Weapon User): 7 (primary fire) / 2 (alt fire)
First Found: Neighbors (Level 3)

The Kungfu Fists are a secret "joke" weapon that are apparently not
meant to be taken seriously. To acquire them, you must read the
secret "Kungfu Zombies" manual found hidden in various locations
throughout the game. Unlike other items, the Kungfu book is NOT
highlighted by the game, and thus you'll miss it unless you know to
look for it. Once you pick up the manual, Jack will utter in a confused
tone of voice "I know Kungfu?" (duh, Neo) and his melee weapon will
be replaced by tattooed fists of fury.

Is this the game you seek??
