Left 4 Dead 2

Overview

Left 4 Dead 2 is a cooperative first person shooter. The game is centered around four characters moving from safe room to safe room, while being attacking constantly by common infected (nothing special npcs) and special infected (infected with unique abilities). The game is centered around an apocalyptic plague that infects the majority of the population, and only a handful of survivors remain.

Gameplay

A multitude of different modes are included in Left 4 Dead 2. In Campaign mode, you and 3 npcs have to move from safe room to safe room while surviving the endless stream of attacks. In Survival mode, your only goal is to survive as long as possible against the constant hordes, competing for awards earned from living for predetermined amounts of time. There is also a mode called Mutation mode, which changes every week or so. A couple game modes that have been includes in Mutation mode are all special infected are Tanks, which is actually a lot of fun, and a mode that has no health packs. All these game modes allow you to play this game for weeks and still not get bored of it.
Score: 95

Graphics

The game is now two years old but the graphics are quite good. The blood and gore from the zombies is extremely detailed, but the game is rarely scary due to the need to just be rushing. You never really get the chance to appreciate much about the maps.
Score: 89

Multiplayer

The biggest part of this game that makes it worth purchasing is by far the multiplayer experience. In the Versus game mode, 4 survivors face off against the infected and 4 special infected. There is nothing more exciting then being the last survivor, dodging the tank and special infected left and right. If this game only included Versus, it would still be worth buying.

Final Score: 94
The game is currently $19.99 on steam, and though it is certainly worth that, the game consistently goes on sale for less than that so it would be best just to wait to get it. You've waited this long, whats another month?
