That's unless you're playing Funny Doors. If you're lucky, you push through the pain and make it into the safe room on borrowed time, grab some ammo and shoot the charging zombies to carve a safe route for the rest of your team. your health bars stripped away by the horde, your eyesight drained of colour, signalling that one more knockdown equals permadeath. Maybe there's only two of your zombie-slaying quartet left.
When you get to the end of a hard-fought round in Left 4 Dead 2, you're usually crawling towards a rugged red door.
