Snowmobiles appear in the Special Ops missions "Time Trial" and "Race". In these missions, the player can get a 'Quick Start!' which allows them to start slightly earlier than normal and gives the Snowmobile a short burst of speed.
The Snowmobile makes an appearance in the campaign mission "Down the Rabbit Hole". Unlike Call of Duty: Modern Warfare 2, it is not controllable. It is only seen when the Ultranationalists attack in the mine's exterior, bringing in reinforcements for defense.
In the Collection 1 content collection, the Snowmobile appears in the Special Ops mission "Black Ice" where one player drives the Snowmobile and the second player shoots from behind with AkimboFMG9s and an ACR 6.8. However, if on solo, the player driving will receive a G18, much like in Modern Warfare 2.
In Call of Duty: Advanced Warfare the Snowmobile appears loaded in the memory for Aftermath under the name "vehicle_jetbike". From the lack of treads and other details it is likely it was used to test the Hoverbike's physics and scripting before the model was complete.
