Today Europe has received a patch for Modern Warfare 2. This patch was suppose to fix a bunch exploits in the game, such as:
    *  Care Package, Emergency Airdrop, and Sentry Gun marker grenades sprint speed normalized
    * Fix for "infinite care package" exploit
    * Sentry Guns: Improved placement detection, preventing cases of Sentry Guns inside geometry
    * Model 1887: Bling using Akimbo and FMJ combination now has same range and damage as non-Bling Model 1887s
    * Improved player collision removing cases of getting into geometry and "elevators"
    * Fixes to prevent various XP hacks
When the patch went live, something unexpected happened. The game kinda didn't work, well at least the most important part of the game, online multiplayer. This, of course, got many people upset and they pulled the patch. US will receive it when its all fixed.
