"A desert training range, with both teams starting on a raised balcony (one with an overhang), each with two ramps; one at either perimeter edge. The side paths each have sand-filled buttress crates and tire stacks, and both widen slightly in the middle. The center of Stack is a raised platform, with plywood stairs (one at each corner), and an open container where the flag spawns."
Stack is a multiplayer map featured in Call of Duty: Modern Warfare that is exclusive to the Gunfight mode. Stack is also available in Call of Duty: Mobile and was added on August 6th, 2021 as part of the Season 6: The Heat update.
