Those looking to get a free taste of Activision’s latest in the behemoth first-person shooter franchise Call of Duty: Modern Warfare 2, will have to wait until after the game is released, and that’s not even a guarantee of anything coming after the game hits shelves. Infinity Ward tweeted that the development staff are hard at work polishing the game, and will take up until the ship date to do so, leaving no time for a demonstration build to be made available. An interesting change of pace for the developer, considering the game’s prequel gave gamers both a multiplayer beta and single player demo.
