Nobody can deny that at times Call of Duty is one of the most frustrating games to play in the world. However, somehow it's one of the most addictive too; absorbing hours of your free time and draining all the colour from your face, except from the dark circles it leaves under your square eyes. They might say 'it's only a game', and although those four words send every gamer into meltdown, it's not only a game - it's a way of life. Global leaderboards, bragging rights and a network of likeminded people all waiting to blow your head off (in the virtual world, of course), there is a lot more at stake than non-gamer's would think. If you're a long suffering fan whose been blighted with the hackers who made World at War a living hell; or the nuke boosters that made Modern Warfare 2 almost unplayable... Just remember, it'll all be worth it when you finally get the hang of it and put in a performance Rambo would be proud of. Here are some of the most frustrating situations you've surely found yourself in over the years. From hackers to quick-scopers, remember to keep telling yourself it'll all be worth it when you unlock that golden camo for your AK-47.
