Call of Duty Modern Warfare 3 Snow Angel Achievement / Trophy Guide
Call of Duty Modern Warfare 3 (2023) Snow Angel Trophy Guide / Achievement Guide - Execute the forest sniper in 'Frozen Tundra' with a takedown
Mission 11: Frozen Tundra
Objective: Escort Shepherd to the Transport
In Mission 11: Frozen Tundra, you will automatically come to a point where you get attacked by a Sniper in the snowy woods. This is the first sniper in the mission. Defeating him is mandatory so you can't miss him. For this trophy you have to do a melee takedown with R3 / Right Stick. This only works when the "Takedown" button prompt appears near the top of the screen, when you are within melee distance to the sniper.
The easiest option is to throw flashbangs at the sniper to stun him, then melee him until the prompt appears and do the takedown. Or just rush in and keep meleeing him until it appears. You can also shoot at him until his armor breaks which will stun him.
The takedown prompt won't always appear so it may take a few tries. If the Sniper dies from other attacks, immediately restart the checkpoint before it saves. Then you can quickly retry as often as needed.
