Left 4 Dead is a highly addictive, tough game.
Ok, to the review.
Left 4 Dead is, as you know, a run and gun zombie killer. In the campaigne you choose from four different players, who are stranded in a city swarming with infected what used to be, civilians of the city. You have to fight your way through the city, picking up and using what ever you can get to help you kill the zombies. You start the game out with a pistol, which has unlimited ammo to use, and you can also find a second pistol so you can duel wield them, which also, both of them have unlimited ammo. Through out the levels, you will find ammo stashes, each holding various weapons, and a pile of ammo for you to fill up on your current weapons.
There is the sub-machine gun, a small, fast shooting gun. This gun is great for those up close moments when those zombies get just too close for comfort.
There are two different shot guns. A pump-action shot gun, which shoots a round, then pumps, then another shot. This shotgun doesn't really help much, but it can take out multiple zombies with one punch. Then you have you semi-auto shotgun. It shoots with the power of the pump-action, with only one difference, it fires as fast as you can pull the trigger! In my opinion, the best gun in this game, it doesn't have to much range, but when those zombies start to gang up on you, it has a massive crowd control. Just start mashing on that trigger button and watch them fall. The only downside to this weapon is it's clip size, it just isn't big enough, and depletes very fast, and it leaves you without a good weapon (not good).
The sniper rifle, I know, a sniper rifle? In a game where zombies run extremely fast and swarm? How can this be useful? I thought the same thing when I first saw it. But actually, it has it's moments. They are few moments, but there are some. Like when you first enter a large area, the zombies aren't exactely stirred up yet and angry. Just tell your teammates to hold back a bit while you thin them out some, work on your head shot achievment.
Of course, you got your everyday assault rifle, it's slower shooting than the sub-machine gun. But it is very accurate and has pretty good crowd control. You can pick off zombies from afar with it, and when they charge, it works too! :)
This game also gives you the feature to play as a "special" infected. There are the smokers, which have to ability to shoot out there tongue and grab a human, making them helpless while you strangle them to death, There is the hunter, which pounces on a human, also making him helpless, while you literally rip his (or her) guts out. You got the boomers, which are very gun, you run around and can puke on people, yes, puke. Once a human has been puked upon, the swarm comes, and is attracted to it, causing that human to have to fight of hundreds of infected. Then, the tank. It's not an actual tank, but darn close. It runs around throwing objects and bashing everything, it takes a crap load of bullets to take down this bad guy.
Overall, this game is a solid buy. It's very fun to play and has mad replay value. The zombies spawn in a different area each time you play. So sometimes, you can sneak around that nasty witch, while others, she spawns right in your patch, forcing you to disturb her. But, this game has it's downfall, like many other games. For this game, it's an absolute must to play with friends, or a group of talkative players. Yeah, there are bots you can use, but they aren't as smart and it just isn't as fun.
Zombies, they never die:)
