Just days ahead of the worldwide release of Modern Warfare 3, Activision has announced that its Call of Duty Elite service will not launch on PC alongside the game.
Furthermore, it isnt currently able to give an ETA.
Were as committed as ever to the PC, but the need to ensure a safe PC environment is greater than ever, Beachhead Studio head Chacko Sonny stated.
Its really extensive. We need more time to get there, so Elite on PC will not launch on day one. Were working our butts off to make it happen, but we wont release it until we know that PC gamers can enjoy Elite as its meant to be.
The issue here is that the PC is an insecure platform. Without a central, trusted resource for stats, a lot of our competition features become unfair. We cant give away prizes when people can easily cheat their stats. Leaderboards are less fun when a lot of the users are there unfairly.
Call of Duty: Modern Warfare 3 will be released across the world on November 8th.
