Modern Warfare 2's Javelin glitch, which enabled a dirty, cheating player to instantly detonate upon death, was fixed earlier this morning by a patch for the Xbox 360 version of the game. According to a recent tweet from Infinity Ward's Robert Bowling, the PS3 version of the game has already received the patch.
In addition to removing the Javelin's unadvertised self-immolation feature, the patch also fixes the equally insidious "unlimited care packages" glitch, and fixes a few areas where players could exploit gaps in the game's geography. In a perfect world, Infinity Ward would have also sent parcels to the houses of anyone who leveraged these exploits -- parcels full of bees. The bad kind. The kind you see on the Discovery Channel. The ones that can kill a full-grown elephant with a surprisingly small swarm.
