Left 12 Dead

Most of you must have heard of the game Left 4 Dead. It's a simple co-operational game which 4 survivors, or players, are put up against a horde of zombies of various kinds. Simple? Well, here's the deal. The number of survivors are increased to various numbers such as 8, 12, 16 or more. Same map, same game, same guns. Nonetheless, it triples the number of survivors, triples the bullet, triples the amount of zombies and triples the fun. Maybe this sounds like some kind of world war 2 games, such as day of defeat, where the enemy now are zombies. Well, that's not exactly false, since the game is designed for 4 players cap, though now we have a chaotic rush of players from one safe room to another. Reminds you of the epic team fortress series. Oh and did I mention that most of these servers are in expert or advanced level? So it means that you'll have to watch out for friendly fire as well, and when tank comes, run like hell.

To search for custom servers, simply type "openserverbrowser" in console and filter the servers according to the amount of players inside/allowed. There are other special servers such as minigun mod (where u can build miniguns) and infinite ammo.

War-like, eh?
One for all, all for one
When you are incapacitated, you are never alone
Climb climb climb~
A strong sense of Team fortress
