Sniper Elite: Nazi Zombie Army 2

This means that playing co-op, you'll probably blaze through the game in about 3-4 hours or so.

Sniper Elite: Nazi Zombie Army 2 builds on the strengths of the first entry with bigger battles, nastier enemies, and an even creepier atmosphere.

Basically Left 4 Dead (L4D) like game, but this game has much better graphics and the zombie killing mechnaics is old fashion(also kill cam!), where the only way to kill them is by headshots, other means like shooting them in the arms or legs or chest, doesn't kill them, they'll fall down but after a few seconds, they'll come right back up and nawling at you!

I'd say its worth it, and to add a boost to the fun, the game permits many different difficulty varieties...

A major part of the game’s charm lies in the exaggerated brutality of its gunplay.

This game is fun,brutal and accompanied by an awesome soundtrack by none other than Nick Brewer who did a very good job on composing the soundtrack for the entire Nazi Zombie Series in general.
