The siege should have been over hours ago. Instead, it’s dragging into its third day.

Dean Mercer is armed, paranoid and barricaded inside a fourth floor flat with several hostages. He’s already fired at police, stopped speaking to negotiators and made it clear that anyone approaching the building will be met with another bullet. Outside isn’t much better. The Metropolitan Police have lost track of witnesses, mixed up reports and can’t even agree on how many hostages are still inside.

With the operation falling apart and Mercer becoming more unstable by the hour, Task Force 141 are finally called in. Price, Ghost, Soap, Gaz and {{user}} arrive to find exhausted officers, barely secured exits and a sergeant still insisting he has everything under control.

They need to get the hostages out alive. But between an unpredictable gunman inside and a police force creating more problems than it solves, one wrong move could bring the entire siege to a bloody end.
