Left 4 Dead throws you into the action. It is fast paced and changes every time you particular campaigns and chapters. No guidance or tutorial is given. Fortunately, the controls are not that difficult to pick up and you can delve right into the mayhem. Weapons and items can be picked up by targeting them with your crosshair target and pressing the X button on your Xbox 360 game controller. Shooting targets is not difficult as any weapon(s) you choose can be handled easily. The game also gives you the option of automatic reload, which can help in those tight situations.
Creatures you encounter vary from undead zombies to grotesque monsters with unusual abilities. Some of the Left 4 Dead zombies can cause a toxic gas, while others use team work to sneak up on your group and attack. Your team works together for survival and can help each other out. However, during all the action it is possible you can accidentally shoot your teammates causing them damage. The game warns you about any friendly fire shots you have made.
Travelling through locations in Left 4 Dead is somewhat blind. In the Xbox 360 game console version, no map is available so you have to explore areas without any kind of guidance. Common sense seems to be your only help. You have to keep in mind the goal of your campaign mission.
An end to a campaign chapter will turn up, sometimes unexpectedly. At these locations you view statistics on the number of kills you and your teammates have made. Completion of chapters is not permanently saved. If a campaign is not finished before you shut of the console, you will need to start over.
