The initial dialogue and the mysterious, misty atmosphere.

The ad opens with two characters, Snake and another soldier, in a misty, purple-hued environment. They exchange dialogue and then shake hands. The scene shifts to a close-up of a device with an alert display. It then transitions to a neon-lit sign that reads "CALYPSO" with two figures holding guns in front of it. The ad concludes with a title card showing "TOM CLANCY'S RAINBOW 6 SIEGE" and a call to action.
