Unleashed on a world waiting to devote entire lifetimes to it's splendour back in 2009, it's funny to think back to those years when the tyrannical internet-buzzword-consuming behemoth of Call of Duty didn't engulf every gaming meme or spring to mind whenever someone mentions online play. Many say this first sequel to the 2007 original that continued the franchise's jump to modern times remains the series' best, contrasting the very well-worn minefield-infested path of the World War II genre by popularising the modern-day shooter like never before. Although going back to a previous COD game is something akin to revisiting an old sports title and knowing that the vast majority of the core fanbase have graduated to whatever the newest annual instalment is, Modern Warfare 2 is that rare kind of military shooter that is actually has a story worth playing through, as well as some perfectly-balanced online combat. Replay it specifically for: Featuring one of the most shocking and talked-about scenes in gaming history in the No Russian level, as well as a huge amount of set-pieces to widen your eyeballs to, with the aforementioned online modes not being overly-complicated or having the burden of forced iteration that plagues the series to this day.
