“Call of Duty Ghosts” – “Deep Freeze” Trophy/Achievement Guide
Drop 8 vehicles into ice holes. [Bronze / 25G]
Mission 10: Clockwork
At the very end of this mission, you will have to escape an enemy facility. While one of your teammates is driving, you will gain control over a grenade launcher turret. Lots of vehicles will come after you. Instead of shooting them directly, you will have to shoot a little bit in front of them to blow a hole into the ground. If they drive over it, the vehicle and its crew will be incapacitated which counts towards this trophy / achievement. Do this to 8 different vehicles before reaching the end of the mission.
