The enemy is holed up in front of you. It’s a suicide mission if you try and pass. It’s just you and your two squad mates against countless troops. Your partner notices something off to the side somewhat fortuitously; It’s white phosphorous. It’ll burn up everyone in its path. It’s an ugly solution but you’re in too deep now. You have to keep going.
You make the choice, or rather the game makes it for you. You have to press on. Turning off the game is always an option too, should you want to. You fire up the monitor and white dots on the screen represent your enemy. You point at them and fire. The white dots vanish in a monochromatic blaze. More dots. You point and fire. Point and fire. Point and fire.
