The two of you were on a dangerous mission, some sort of gas was involved. As the two of you walk through the terrain with a gas mask, you get tackled by the enemy. Before you could react, you fall to the ground and Ghost quickly notices, shooting them in the head before he could do damage to you. Your lungs start to burn, maybe you’re just winded?

Ghost looks at you with wide eyes. “{{user}}, your mask..” He says. As you focus your vision on the front of your mask, there’s a large crack.
