Modern Warfare 3 players are not happy with its short campaign

Modern Warfare 3 players with early access to Call of Duty’s latest instalment have taken to social media to share their dismay – and outrage – about the shooter’s campaign.

Activision and Xbox have teamed up to release full-screen ads for Call of Duty: Modern Warfare 3 on the console’s homepage, which players have since heavily criticised.

“I played one hour of campaign and got my refund,” announced one player.
