Zombies, one of the oldest horror creations. Throughout the years, the brain chewing has been mixed with neck-ripping and general flesh eating. The causes of zombiefaction are similar: Viruses, rabided animals, government made weapons, cures-that-went-wrong and I believe even alien diseases. What ever the cause, you are bound to see moaning zombies, with blood and gore everywhere. While most games have made zombies slow walking, easy targeted mobs, with the odd "super-fast zombie" (Half-Life 2 for example).
Left 4 Dead gets rid of that cliché, all zombies (or Infected) run towards you, just like normal people. Screaming, and making general noises. If they are not sprinting towards you, they are crying, leaning against walls, shambling around, vomiting, or indeed fighting each other to death.
Now this is where I think the L4D Zombies are brilliant. They are just like 'normal' people, they don't have super sharp teeth that can break your skull or rip your neck open. No, they just run over and start kicking and punching you. If you are knocked over, they will begin to kick you to death. Finally! A game that warrents the players to have a "life bar". As you are only being kicked and punch, it warrents you to be able to take a lot hits from the zombies, instead of you being the bullet-absorbing macho muscle ridden / hot guy character.
On to the characters themselves, they are incredibly believable, well voice acted and are dressed like 'normal' people. No super-mega-awesome armor of awesomeness that has a nuke build in the collar. They are fantastic, and nothing breaks the fear than Francis saying "I hate hospitals...and laywers..." only for Bill to reply "Is there anything you don't hate".
Valve plan to release films on each of their characters and their background. Their names are, Bill, Louis, Francis and Zoey. Bill is an old 'war veteran' who smokes. Louis is an office worker, and has a similar look to that of Shaun in Shaun of the Dead. Francis is a typical macho muscle guy, who is a biker. While Zoey is a 'attractive' girl, who sounds 'hot' as well as 'looks'. You get to choose one of these characters in the game Lobby, and they are all similarly adapted and blowing a zombie head off (In spectacular style!).
There are three modes, Single Player, Campaign Mode and Verus Mode. There are five maps, all are playable in Solo mode and Campaign Co-op mode. All 'campaigns' are split into several maps.Unfortunatly only two are availble in Versus mode. Which is a shame, as all the maps are awesome, and Versus mode is the best mode of them all.
Speaking of Versus mode. This is a brilliant idea, not only do you play as the Survivours, but you play as the Super-Zombies (boss). These are 'special' zombies which have different looks and abilities to other 'normal' zombies, each are fun to play and are even more fun when your working together to kill your friends. The special zombies are: Hunter - Fast, high jumping hoodie zombie, that pounce on survivours and rip their skin off. Smoker - Long tounge that pulls survivours towards them and drains their life. Boomer - Vomits on players which summons a horde to come attack the target. It also blinds the survivours when it explodes near them. Tank - The best one of them all, big and powerful, able to life up scenary and throw it, take lots of hits, and hit cars towards people. You swap teams at the end of each 'level' so no hogging on zombie side. The Witch is an unplayable Special Zombie, but She is very powerful, when you buy the game, you'll see why.
Over all, this game is amazing. Not enough characters in this review to explain it. Only poor points are limited maps in versus mode and weapons.
